p. 185, 1907), but it has the setulose lobe with which _ in 

 Racovitza's genus the mandible is not equipped. The first maxillae 

 have eight spines on the outer plate, whereas in Paraphiloscia 

 stenosoma Stebbing (Willey's Zoological Results, part v. p. 648, 

 1900) they have only three apical spines on that jslate. The 

 outer margin of that plate is more strongly sinuous and less 

 uniformly fringed than in P. muscorum. The second maxillfe 

 have the inner setulose lobe distinctly defined and the much 

 broader outer lobe undivided ; while in P. muscorum the outer 

 lobe is longitudinally cleft and the setulose lobe has no distinct 

 lower mai-gin, nor is this margin mentioned by Racovitza, in 

 whose species the second maxilla otherwise resembles that of 

 Anchiphiloscia. In the maxillipeds the articulation between the 

 second and third joints of the palp is in this genus discernible 

 under high magnification. Racovitza declares this palp to be 

 clearlv only two-jointed in A. simoni. In the latter species the 

 telson is almost semicirculai-, in the species referred to the present 

 genus it is triangular. The two species in question are in many 

 respects in close agreement, but one of them has the pleon 

 abruptly narrower than the perfeon, with the lateral apices of the 

 pleon segments inconspicuous from above, while in the other 

 the narrowing of the pleon is far less abrupt, and the apices of 

 the third, fourth, and fifth segments as seen from above are well 

 separated and conspicuously displayed. 



The generic name is compounded of ayx'j near, and Philoscia. 



Anchiphiloscia karong^, sp. n. (Plate XXVIL, A.) 



This species shows a close resemblance to Philoscia suarezi 

 Dollfus, from Diego Suarez in North Madagascar (Mem. Soc. 

 -Zool. de France, vol. viii. p. 185, fig. 7 in text, 1895), of which, 

 however, the mouth-organs are not described. Independently of 

 these, other features seem to make the identification inadmissible. 

 These affect the second antennae, the uropods, and the telson. 



The body is rather naiTowly oval, the head not broad, the last 

 peraion segment strongly arched over the pleon and then turning 

 obliquely outwards on either side, not forming acute apices. The 

 pleon is brusquely narrower than the perseon, and the adpressed 

 lateral angles of the third, fourth, and fifth segments are not 

 discernible from above. The telsonic segment is broader than 

 long, with the sides straight, but the point not blunted as in 

 P. suarezi. 



The sides of the head curve in towards the front, with the eyes 

 sitviated at the angles so formed. The small first antennae have 

 the second joint intermediate in thickness between the stout first 

 and tapering third, the latter being scai-cely longer than the 

 second, and a little shorter than the first. The second antennae 

 are longer than half the body, the second joint a little longer 

 than the third but much shorter than the fourth, the fifth nearly 

 as long as the third and fourth combined and as long as the 

 flagellum ; in this the first joint is longer than the second, but
