Lambrus lamellifrons Adams & White, Voy. Samarang, Crust., 26, pi. v, fig. 1, 1848. 
Carapace with rostrum a little longer than broad, its surface covered, though not closely, with 
granulated tubercles and cylindrical blunt spines. Five median spines, one gastric, three cardiac, one 
posterior marginal; two side by side on gastric in front of median; one large branchial spine forming 
the middle one of a longitudinal Curve of three; on antefo-lateral margin of branchial region a row of 
about eight small spines. Hepatic region prominent, with one noticeably long spine. Orbital region 
prominent, carapace distinctly constricted behind it. A spine on dorsal surface of each supraocular 
eave; Rostrum strongly deflexed, narrow, armed with two or three small spines on each side. 
Chelipeds in adult female from two to two and two-fifths times as long as carapace; covered with 
sharp and gfanulated tubercles, and on the margins rough triangular spines. Anterior or inner margin 
of arm with about five long spines and at the distal end three or four smaller ones; above a row of 
about eight very uneven spines and on the outer margin two or three large ones. On inner margin 
of hand about-six large spines, on outer margin five to seven large ones, and two or more on upper 
surface. Spines of lower margin of cheliped small, but fairly uniform and very jagged. 
Legs almost smooth, armed only with a few rough tubercles; transversely banded in two colors. 
There are only two large specimens (females) in the collection; the largest, which is laden with 
eggs, has the prominent spines much less developed — that is, lower, blunter, and more tuberculiform 
than in the specimen slightly smaller. The largest male is 14 mm. long, and its chelipeds are just as 
long in proportion to the carapace as in the adult female. Small specimens are much smoother than 
large ones, one the same size as that shown by Adams and White (loc. cit. ) agreeing very well with the 
figure. 
Dimensions. — Female, station 3861, length 51.2, width 49.5 mm. 
Distribution. — South coast of Molokai Island, 23 to 66 fathoms, stations 3847 and 3850; Pailolo 
Channel, 30 to 52 fathoms, station 3861; Auau Channel, 13 to 43 fathoms, stations 3871, 3874, and 
3876; vicinity of Kauai Island, 237 to 164 fathoms, station 3984; vicinity of Modu Manu, 23 to 56 
fathoms, stations 4146 and 4164. 
This species seems not to differ much from P. (R. ) longispina Miers. (See Alcock, Jour. Asiat. 
Soc. Bengal, LXIV, 1895, 266.) The rostrum, however, is narrower and armed along the sides and 
there is only a single spine on the posterior border in the middle line. 
Parthenope (Aulacolambrus) hoplonotus (Adams & White). 
Lambrus ( Aulacolambrus ) hoplonotus Alcock, Jour. Asiat. Soc. Bengal, LXIV, 1895, 273, and 
synonymy. 
East coast of Maui, A. Garrett, 1 dried specimen, in Museum of Comparative Zoology. 
Parthenope (Aulacolambrus) whitei (A. Milne Edwards). 
(PI. xv, fig. 5.) 
Lambrus ( Aulacolambrus ) whitei Alcock, Jour. Asiat. Soc. Bengal, LXIV, 1895, 274. 
South coast of Molokai Island, 23 to 24 fathoms, station 3847; 1 male. 
This specimen differs from the figure given by Adams and White (Voy. Samarang, Crust., pi. v, 
fig. 3) in the following particulars: 
The median spines are much lower; the tubercles and granules of the carapace are more numerous; 
the large lateral spine extends further sideways; on its posterior base are two teeth; the submedian 
pair of spines on the posterior margin are very much smaller.
