Decapod Crustacea of Bermuda, Part II. 123 



Jousscaumca ortmanni Coutiere, C. R. Acad. Sci., Paris, vol. cxxxi, p. 

 356, 1900. 



Rostrum slender, acute, extending slightly beyond the second 

 joint of the antennules. Eyes concealed by a hood ; edge of hood 

 with a minute acute spine; below the eyes the margin of the 

 carapace is very oblique. Spine of antennules reaches the distal 

 end of the second segment. Antennal scale is about as long as 

 the peduncle of the antennules. Larger chela is smooth, entire, 

 short, thick, swollen, length twice the breadth; fingers slender, 

 hooked, and serrulate on the cutting edges. Carpus of second leg 

 is 5-jointed ; first segment is equal to the four distal ones. Telson 

 narrow, compressed; margins smooth. Length about i6mm. 



Bermudas, coll. G. B. Goode, I specimen (M. J. Rathbun) ; 

 New Providence, Bahamas (Rankin, type-locality). It was not 

 taken by us nor by later collectors. Its habits are not known. 

 It may live in sponges. 



Amphibetaeus simus (Guerin). 

 Alpheus simus Guerin, op. cit., 1857, pi. 



PLATE XXV, FIGURE 5 (after Guerin). 



This species seems not to have been rediscovered since the time 

 of Guerin. However, I have a similar specimen, apparently of the 

 same species, taken among branching corals and sponges at 

 Dominica Island in shallow water several years ago by A. H. 

 Verrill. It appears to belong to the genus Amphibetaus of 

 Coutiere (op. cit, p. 325). 



The frontal region is convex, produced far over the eyes, with- 

 out a rostrum or distinct ocular lobes. The antennular stalk is 

 elongated; the second segment being much longer than the first 

 or third ; stylocerite is short, foliate ; carpocerite is about equal 

 to the antennular stalk ; scaphocerite is of about equal length, with 

 a well formed scale ; basicerite is short, dentiform. Guerin's type 

 was from Cuba. 



Family HIPPO LYTID^E .Bate, 1888. Shrimps. 

 Eyes not covered by the carapace. Rostrum well developed, 

 usually toothed. Chelae of first pair of legs not unusually large, 

 nor very unequal ; second pair slender, with the carpus variously 

 segmented, and the chelae small.
