414 THE DECAPODA COLLECTED BY THE " HUXLEY " FROM THE 



Uroptychus nitidus var. concolor (A. Milne-Edwards). 

 Station XIII. 412 fathoms. One, 30 mm. 



Uroptychus Bouvieri, Caulleiy. 



Station XIII. 412 fathoms. Three, 14-5-22 mm. 



This is the first time this species has been recorded since it was 

 described by Caullery.* The type specimens, two males, were found 

 by the Caudan expedition between 218 and 273 fathoms. 



Two of the examples collected by the Huxley are ovigerous 

 females, and measure 22 and 20'5 mm. from the tip of the rostrum to 

 the apex of the telson ; the third is a male, 14'5 mm. in length. The 

 first pereiopods measure 26, 24, and 23"5 mm. respectively, thus 

 showing that this limb is much more strongly developed in the male 

 than in the female. 



Little can be added to Caullery's careful description. The small 

 median denticle behind the base of the rostrum is absent in all the 

 specimens, the lateral spines on the carapace vary in number from five 

 to six, and the antennal scale reaches to two-thirds the length of the 

 rostrum, and is narrower at its base than in the figure of the type. 

 The notch in the sternal plaston is, in the female, rectangular in shape, 

 and considerably deeper than in the male. 



Only four longitudinal rows of spines can be found on the merus 

 and carpus of the first pereiopod, and the internal edge of the propodus 

 of the same limb is upturned and denticulate proximally and is 

 separated from the smooth dorsal surface by a well-defined groove. 



The eggs, which appear to be on the point of hatching, measure 

 about 1"5 mm in length. 



Gastroptychus formosus (A. M.-Edw. and Bouvier). 

 Station VII. 444 fathoms. One, IS mm. 



„ XIII. 412 fathoms. Two, 21 and 38 mm. 



One of the specimens from Station XIII is an ovigerous female.
