Parthenope ( Parthenolambrus ) calappoides (Adams & White). 
(PI. xv, fig. 6.) 
Lambrus (Parthenolambrus) calappoides Alcock, Jour. Asiat. Soc. Bengal, LXIV, 1895, 275, and 
synonymy. Borradaile, Fauna and Geogr. Maidive and Laccadive Arch., II, 1903, 690. 
Distribution. — South coast of Molokai Island, 43, to 66 fathoms, stations 3845, 3846, and 3850; Auau 
Channel, 28 to 43 fathoms, station 3876; vicinity of Kauai Island, 40 to 233 fathoms, stations 3982, 
3987, and 4002; northeast coast of Hawaii Island, 24 to 83 fathoms, station 4061; vicinity of Kauai 
Island, 68 to 179 fathoms, station 4128; vicinity of Modu Manu, 26 to 56 fathoms, stations 4148 and 4164. 
This species, as Alcock has said, is very variable. In most specimens the regions are not 
carinated nor sharply raised; in some, however, notably those from, stations 3982 and 4164, there is a 
very high nodule on the gastric and on the cardiac region, the branchial region has a rather strong 
carina, with a tubercle at its middle, the hepatic region is narrowed and thickened and in consequence 
widely separated from the branchial region, the supraocular lobes are extremely high. Between this 
form and the typical are gradations, even in individuals from a single station, as 4061. 
Another remarkable variety is represented by an ovigerous female from station 4148. This form 
varies in a different way from the typical, and were it not for the extraordinary diversity which I have 
found in other species of Parthenope , e. g. , P. stellata and P. nummifera, I should describe it as a distinct 
species. All the margins of the carapace are more spreading, the front is less vertical, the posterior 
margin forms a more produced lobe, the antero-lateral border is more limb-like, the lateral angles are 
strongly upcurved. A long gastric and cardiac spine. Surface of carapace and chelipeds crisply gran- 
ular and margins of the latter sharply dentate. On the proximal half of upper margin of palm a very 
thin lamellar lobe with crenated edge. In other specimens this lobe is either absent altogether, as in 
the typical form, or represented by a thick blunt nodule, as in the nodular variety from station 3982 
described above. 
Daldorfia horrida (Linnaeus). 
(PI. xiv, fig. 5.) 
Parthenope horrida Alcock, Jour. Asiat. Soc. Bengal, LXIV, 1895, 279, and synonymy. 
Distribution. — Auau Channel, 21 to 43 fathoms, stations 3872 and 3874; Hilo, Hawaii, H. W. Hen- 
shaw; Oahu, H. Mann, in Museum of Comparative Zoology. 
Hawaiian Islands (Randall); one large male, J. K. Townsend, collector, in 
Philadelphia Academy of Natural Sciences. Laysan Island (Lenz). 
In the two larger specimens the teeth of the legs are triangular except on 
upper margins of merus joints, where, in the male from station 3874, they are 
scythe-shaped, the point of each scythe touching or overlapping the convexity 
of the next, so as to leave orbicular interspaces; in the male from Hilo, the 
“scythes” have two points in opposite directions and the base of the sinuses 
is denticulate. 
The sternal hollow in the largest and smallest male is subtriangular with 
corners rounded; in the male from station 3874, it is transverse oblong with a shallow median parti- 
tion. There is also a line of smaller cavities on either side of the male abdomen. 
Harrovia truneata, sp. nov. 
(PI. xiv, fig. 8.) 
Carapace hexagonal, a little broader than long; elevated portions finely granulate, depressions 
smooth. Three gastric elevations corresponding to the regional subdivisions; a transverse curved fold 
or elevation running across the cardiac and part way across the branchial region; smaller and lower 
nodules on the anterior branchial and hepatic areas. 
Front slightly deflexed, truncate, divided into two feebly concave and oblique lobes by a small 
notch, and separated by a faint-groove from the inconspicuous orbital angle; edge double, granulate. 
Two teeth of moderate size, at lateral angle; at posterior base of the last one a much smaller tooth; 
a notch at middle of postero-lateral margin which is thick and coarsely granulate. A single line of 
granules on posterior margin.
