three times as long as broad ; outer margin slightly 

 concave, ending in a strong tooth; lamella of 

 scale exceeding spine; outer spine near base of 

 scale directed ventrally. 



Epipods on first four pairs of legs small but 

 distinct. First legs equal, reaching somewhat be- 

 yond end of antennal peduncle; fingers short and 

 blunt, immovable finger ending in a dark colored, 

 sharp point fitting between two dark points on 

 end of dactyl, outer surface of fingers convex, 

 inner surface concave, fingers about five-eighths 

 length of palm ; carpus slightly shorter than chela 

 and three-fourths length of merus. Second legs 

 slender; slightly unequal in size, reaching almost 

 to end of third maxilliped; chela small and 

 slender; carpus five times length of chela and 

 divided into 13 to 15 joints, first and last joints 

 longest. Third to fifth legs slender; dactyls 

 simple. 



Abdomen coarsely and shallowly pitted; third 

 segment with a dorsal carina ending in a strong, 

 posteriorly directed spine; pleura of second to 

 fourth segments produced postero vent rally in a 

 narrowly rounded tip, pleura of fifth and sixth 

 ending in a distinct sharp tooth; posterolateral 

 angle of sixth spiniform. Telson tapering grad- 

 ually to a slender point; dorsal surface with two 

 pairs of spines, anterior pair at one-third length, 

 second pair closer to first pair than to tip. 

 Uropods elongate ; outer margin of exopod ending 

 in two distinct teeth, between these a slender 

 movable spine. 



Measurements.— Length of body : ovigerous fe- 

 males, 47 to 79 mm. 



Variations. — In the case of a rostrum with one 

 distal tooth dorsally, there were suggestions of 

 three other small, malformed teeth. 



Color. — General color pink; rostrum and an- 

 terior part of carapace pink, posterior part of 

 carapace white and yellowish; abdomen white 

 with pink most pronounced along posterior mar- 

 gins of first to fourth segments, spine on third 

 segment almost red, fifth and sixth segments 

 entirely pink; tail fan red, pink at base; anten- 

 nular and antennal flagella pink; legs red, some- 

 times purplish distally ; pleopods red; eggs yellow 

 or greenish (Holthuis, 1959). 



Habitat. — The species has been taken near shore, 

 often in estuaries (15.89 °/ ot> over mud bottom) 

 (Holthuis, 1!);.!)) ; 4 to 15 fathoms. 



Type locality. — Mouth of Suriname River near 

 Resolutie, Surinam. 



Known range. — Off Cape Fear River, N.C., to 

 Port Aransas, Tex.; British Guiana to Santos 

 Harbor, Sao Paulo, Brazil. 



Remarks. — Most information on this recently 

 described species is summarized in Holthuis' 

 (1959) account. Ovigerous females have been re- 

 ported from December to July in South America 

 and from August to October in the Carolinas. 

 The species is more abundant than Xiphopenew 

 in British Guiana but apparently less abundant to 

 the eastward in the other Guianas. Records from 

 the United States are sporadic. 



Family Processidae 



Rostrum horizontal with dorsal surface of cara- 

 pace. First pair of legs asymmetrically chelate; 

 first leg of one side ending in a simple clawlike 

 dactyl. Second pair of legs minutely chelate; 

 slender ; with segmented carpus.

Recognition characters. — Rostrum slender, near- 

 ly straight, extending about two-thirds length 

 of eye, bifid at end with upper process shorter 

 than lower, a few hairs between tips. Carapace 

 lacking antennal spine; anterior border rounded, 

 somewhat sinuous. Eyes large, shorter than basal 

 antennular article. Antennular peduncle with 

 basal article excavate dorsally, longer than suc- 

 ceeding two articles combined, stylocerite short, 

 somewhat truncate; second article about half 

 again as long as third; inner flagellum filiform; 

 outer flagellum thick, fusiform at base, slender 

 distally, hairy, about as long as peduncle. An- 

 tennal scale about six times as long as wide; sides 

 nearly parallel, truncate terminally; lateral spine 

 small, slightly exceeding lamella; antenna a little 

 longer than body. Third maxilliped with ter-
