BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Color, pale yellow; fingers brown (A. Milne Edwards). 
Dimensions of male: Length, 6.2 mm.; width, 8.5 mm.; fronto-orbital width, 5.5 mm.; frontal 
width, 2.8 mm. A young male measures 3.3 mm. long by 4.2 mm. wide. 
The specimen described by A. Milne Edwards was intermediate in size and also in proportionate 
width between the two taken by the Fish Hawk. It will be seen that our largest example is consid- 
erably wider than the type, also more oval and shows two additional lateral teeth. In the smaller 
example, the second lateral tooth is scarcely distinguishable; the fifth almost obsolete. I have little 
doubt, therefore, that these are the veritable Eucratodes ctgassizii, a rare species, not having been 
recorded since its original description. 
Off Aguadilla, 137 fathoms, station 6055; Mayaguez Harbor, 161 to 172 fathoms, station 6066. 
In regard to the type locality, the west coast of Florida, 100 fathoms, is the locality accompanying 
the original description; but in the Bull. Mus. Comp. Zool., vm, 14, the locality is given as lat. 21° 
14' N. , 100 fathoms, Stimpson, collector. This entry is probably a corrected one. Dr. Stimpson made 
a series of dredgings in the Yucatan Channel while on the U. S. Coast Survey steamer Bibb. 
Genus CHLORODIELLA Rathbun. 
Chlorodius Milne Edwards, Hist. Nat. Crust., I, 399, 1834. (Not Clorodius Leach in Desmarest, 1823.) 
Chlorodiella Rathbun, Proc. Biol. Soc. Washington, xi, 157, 1897. 
Carapace depressed, flat, hexagonal, the regions partially or not at all demarcated, surface smooth 
and almost unbroken, except sometimes anteriorly and on branchio-hepatic region, near antero-lateral 
border, where there may be some .broad transverse wrinkles. Fronto-orbital border varying from 
about two-thirds to more than three-fourths the greatest breadth of carapace. Front almost straight, 
emarginate in middle line, extremely broad (between a third and a half the greatest breadth of 
carapace), its outer angles separated from the supra-orbital margin by a groove. Antero-lateral borders 
cut into four lobes or teeth. Postero-lateral borders rather longer than the antero-lateral. Orbit with 
two suture lines above and one at the outer angle; eyes on short thick stalks. Basal antennal joint 
large, extending upwards and outwards into gap between front and orbit; flagellum in crevice-like 
orbital hiatus. Merus of external maxillipeds with anterior border almost transverse. Chelipeds 
unequal, long, more than twice the length of carapace, half or more of arm projecting beyond edge of 
carapace; fingers large, broadened, and deeply hollowed at tip. Legs spinulous. Abdomen of male 
consisting of five joints, the third to fifth somites being fused. 
Chlorodiella longimana (Milne Edwards). 
Chlorodius longimanus Milne Edwards, Hist. Nat. Crust., I, 401, 1834. 
CJlZorodiella longimanus Rathbun, Ann. Inst. Jamaica, i, 14, 1897. 
Gastric region faintly indicated. Smooth transverse ridges on the epigastric, protogastric, 
hepatic, and anterior branchial regions. Postorbital and branchio-hepatic furrows deep. Antero- 
lateral borders cut into four teeth besides orbital, the first two obtuse and tuberculiform, the last two 
longer and acute. Front with a double edge, the upper one truncate, feebly notched in middle, the 
lower one with a deeper notch, and oblique lobes projecting beyond upper; outer corners turned 
down to meet antennal joint. Anterior margin of merus of outer maxillipeds has a moderately deep 
sinus. Chelipeds very long; two-thirds of arm projects beyond carapace, its anterior margin armed 
with four or five teeth or spines; wrist smooth and bearing a spine or a tubercle at inner angle; hand 
long and smooth; fingers stout and black, the black color of pollex extending a little on hand. Legs 
granulous above and hairy. 
Dimensions of male: Length, 14 mm.; width, 22.5 mm.; fronto-orbital width, 14.4 mm.; width 
of front, 7 mm.; approximate length of clieliped, 46 mm.

Genus MENIPPE de Haan. 
Menippe de Haan, Fauna Japon., pp. 4 and 21, 1833. 
Carapace broad, transversely oval, moderately convex fore and aft, very slightly so from side to 
side; regions, except gastric, little defined. Antero-lateral borders long, strongly arched, cut into four 
teeth besides orbital; postero-lateral borders slightly shorter than antero-lateral, convergent; posterior 
border short. Front narrow, a fifth or less than a fifth the greatest breadth of carapace, rather 
prominent, almost horizontal, cut into two lobes, the outer angle of each of which forms a distinct
