male composed of seven segments ; that of the adult female of five 

 segments. 



The species are found in the Indian Ocean. 



H. Aries, Length about an inch. 



Halimus Aria, 

 a, head in detail ; b, eye ; c, pcdipalp. 



Acanl>umyx(L&trei\le). Carapace nearly as elongated as in Halimua, 

 but less convex, and much less spiny ; rostrum horizontal, and formed 

 of two flattened and divergent horns ; orbits circular, and occupied 

 entirely by the base of the ocular peduncle, which passes beyond 

 them remarkably. Disposition of the antennae, of the epistome, and 

 of the jaw-feet nearly the same as in Ifalimut. Feet short and stout ; 

 those of the last four pair very much compressed ; fifth joint enlarged 

 below, notched near the end with a hairy tooth, against which the 

 finger is bent back in manner of a claw; those of the second pair 

 show this structure most clearly. 



The form is widely spread. Species are recorded from the Mediter- 

 ranean, from the Antilles, and from the Cape of Good Hope. 



A. lunulattu. Length about 8 lines; body smooth, with some 

 fasciculi of hairs on the front; colour deep green. It inhabits the 

 coasts of Provence and the Bay of Naples, where it is found in 

 crevices of the rocks overhung with A Igoe. 



Acanthuityx lumilatu*. 

 a, bead in detail ; b, eje ; e. termination of foot of second pair ; d, antenna. 



Epialttu (Milne-Edwards) Establishing in some respects, according 

 to the opinion of M. Milne-Edwards, the passage between Dodea and 

 Acanthonyx, but much more nearly approximated to the latter. 

 Carapace between circular and hexagonal, scarcely longer than it is 

 wide, regularly convex and smooth above ; rostrum narrow, triangular, 

 and little or not at all divided ; latero-anterior borders of the carapace 

 very short, and forming with the lateral borders a very open angle ; 

 eyes very short, and not projecting much beyond the orbit, which is 

 circular and with entire borders : but the eyes nevertheless appear 

 susceptible of being recurved a little backwards; antennary region 

 very small ; moveable stem of the external antenna: inserted under 

 the rostrum, at a considerable distance in front of the orbit, and the 

 basilary joint of these appendages nearly triangular, and very narrow 

 nt its extremity. It would seem to form ihe whole of the lower 

 orbitary wall. The second joint of these antenna; is a little enlarged, 

 and nearly twice as long as the third ; epistome small and square ; 



external jaw feet- large, and their third joint nearly square, not 

 sensibly enlarged externally, and only a little notched at its anterior 

 and internal angle, where it joins to the succeeding articulation ; the 

 sternal plastron nearly circular ; anterior feet rather strong, and the 

 claws slightly spoon-shaped ; the succeeding feet cyliudrical, and on 

 their penultimate joint a small setiferous tubercle more or less 

 projecting ; their last joint is furnished below with two rows of small 

 spines, and has but little flexibility : the tubercle is only well apparent 

 in the posterior feet; the second pair are much longer than the 

 others : segments of the abdomen varying from six to seven in 

 the male. 



The species are found on the coasts of Chili, as far as is yet 

 known. 



E. tuberculatus. Length 3 or 4 four lines ; colour brownish-yellow. 

 It is a native of Chili. 



Epialtiit tuberculatus. 



Leucippa (Milne-Edwards). M. Milne-Edwards sees iu Leucippa 

 much analogy to Acanthonyx, and he is of opinion that the former 

 establishes in some points a passage between the Maians and the 

 Parthenopians. Carapace resembling that of Emynome, save that 

 instead of being unequal and beset with spines as in them, its surface 

 is perfectly smooth ; its length exceeds its width only a little, its 

 anterior portion is nearly triangular, and its latero-anterior borders 

 are projecting and trenchant; rostrum horizontal, projecting, very 

 wide, and formed of two lamellar horns ; orbits incomplete, so that 

 the eye cannot be hid therein completely; the superior border of 

 these cavities is straight, and goes to rejoin the base of the first 

 tooth from the latero-anterior border of the carapace, so as to form 

 a triangular notch ; the external edge of the basilary joint of the 

 external antennae constitutes the internal portion of their inferior 

 wall or partition : but backwards and below they are limited by 

 nothing, and it may be said that there is no post-foraminary portion 

 of the orbit ; the eyes are small, and carried on a very short peduncle : 

 when they are folded backwards they only reach a little beyond the 

 transversal line, and they are applied on the angle of the latero- 

 anterior border of the carapace ; the first joint of the external antennae 

 is straight throughout its length ; the second and the third are com- 

 pletely hidden under the rostrum, and this last is nearly twice as 

 long as that which precedes it ; epistome not very much developed ; 

 external jaw feet with their third joint very much dilated outwards, 

 and slightly truncated at its anterior and internal angle ; feet short, 

 compressed, and surmounted nearly throughout their length by a 

 trenchant crest ; abdomen of the female composed of seven segments, 

 and covering the whole of the sternal plastron : that of the male 

 unknown. 



This form, as far as is known, belongs to the Pacific Ocean. 



L. penlagona, the only species, is about four lines in length ; colour 

 pale-gray (female). 



Leucippa pentagons.

MA'LABATHRUM, a name which occurs frequently among the 

 writings of the ancients, and which was applied to a leaf imported 

 from India, whence it was likewise called <piiM.ov 'lv$H<6v, and also 

 simply Folium. It was employed by them both as a medicine and 

 as a perfume. From it there was prepared both an oil and a wine 

 by maceration of the leaves in these menstrua. Many fabulous state- 

 ments accompany the earliest accounts, as that of Dioscorides, by 

 whom it is stated that by some they are thought to be the leaves of 

 the Indian Naud ; that they are moreover found floating on Indian 

 marshes, and that they grow without roots (lib. i., c. 11), and that (lib. 

 ii. c. 10) it is by feeding on them that the animal affording the Ony- 

 chia, or Unguis Odoratus of the ancients, becomes aromatic. In the 

 works of the Arabs Saduj is given as the synonyme of MalaJiathrum ; 

 and Saduj, both in Persian works and in India, is applied to Tej-Pat, 

 or the leaf of the Tej, which is a species of Cinnamomum, C. albijlorum, 

 growing in the dense forests of the valleys of the Himalaya, which 

 extend from Rungpore to the Deyra Doon in 30 N. lat. Dr. Hamilton 

 found the same name applied to a very nearly allied species, the
