Genus EUCINETOPS Stimpson. 
J??flcmefop$-Stimpson, Arm. Lye. Nat. Hist. N. Y., vn, 191, I860. 
Carapace oblong. Rostrum small, bifid, little deflexed. Eyes very long, reaching much beyond 
the margins of the carapace. Orbits small, inclosing only base of eye peduncles; external angle acute, 
spiniform; superior margin with one fissure, without teeth and spines. Antennular foss:e not deep, 
round, margins obtuse. Basal article of external antennae small, armed at external angle with a minute 
tooth or spine; movable part depressed, first and second articles very broad. Epistome very short or 
wanting. Buccal cavity very broad anteriorly. Merus of outer maxillipeds longer than broad, outer 
front angle prominent; palpus swollen at base; exognath reaching beyond endognath anteriorly. 
Eucinetops blakiana Rathbun. 
Eucinetops blakiana Rathbun, Proo. IT. g. Nat.. Mus., xix, 13, 1896. 
Antero-lateral margins slightly converging anteriorly, nearly straight. Surface uneven; median 
regions elevated, hepatic region depressed, separated from branchial by a deep hollow and a marginal 
sinus. Antero-lateral margin tuberculate, a spine at postern-lateral angle; a few additional tubercles 
on upper surface of branchial region. Front depressed, with two rounded lobes, tipped with a small, 
sharp spine and separated by a V-shaped sinus. Outer orbital tooth longer than broad, acute, 
upturned, separated from upper margin of orbit by a narrow, rounded sinus. Eye-stalks filling orbit, 
tapering to near cornea; tip sliglitly enlarged. Antero-external lobe of first movable joint of antennae 
moderately developed, not reaching end of rostrum. Abdomen composed of seven free segments in 
both sexes; in the male constricted at fifth segment; sixth segment with convex lateral outlines; 
seventh rounded, broader than long. Chelipeds small, smooth, and shining; merus sub trigonal; 
carpus with a tubercle above, near merus; hands compressed, margins converging toward fingers. 
Ambulatory legs subcvlindrical; dactyli very slender and much curved. Carapace and ambulatory 
legs, clothed with hair. 
Length of female, 6.4 mm.; width, 4.6 mm. 
Arroyo; one immature female. This specimen differs from the types in having a small spine at 
outer angle of basal joint of antennae. In the types the tooth at that angle is more strongly developed 
in the male than in the two adult females. Port Royal, Jamaica (type locality); Bahama Banks. 
Genus COLLODES Stimpson. 
Co^odes Stimpson, Ann. Lye. Nat. Hist. N. Y., vix, 193, 1860. 
Carapace ovate- triangulate. Rostrum short, entire or bifid. Postorbital process large, triangular, 
separated from supraorbital arch by a deep, open, marginal fissure. Eyes of moderate length, 
partially retractile. Basal joint of antenna with a terminal tooth or spine and two margins more or 
less dentate, the inner margin in a plane at right angles to the outer; flagellum longer than rostrum. 
Merus of outer maxillipeds obcordate, deeply cut on distal margin, strongly produced at outer and 
inner angles. Chelipeds of moderate length; merus trigonal, curved. Ambulatory legs of moderate 
length, the first pair a little more than twice the length of carapace; second pair about the same 
length as first, sometimes longer; third pair usually shorter than either; four+h pair the shortest. 
Dactyli styliform, capable of being folded against penultimate joints, and so forming a sort of anchor by 
which the animal can attach itself to foreign substances. 
Abdomen of male with six, of female with five segments. Surface usually hairy, the hairs col- 
lecting and retaining particles of mud; upper surface of legs furnished with curved hairs, lower surface 
with long, straight hairs or bristles.
