very convex from the upper to the lower margin ; convexity akin to 

 that of the manus of this species, which is the reason for placing 

 the carpus here rather than with Gallianassa elongata or any other 

 species occurring at the same localhy. Carpus about If times as 

 high as its greatest width, which is in the upper part; the angle 

 formed by the superior and the distal margins is a little less than a 

 right angle ; superior margin straight ; distal angle projecting above 

 the articulation with the manus. The inferior distal angle projects 

 even more below the articulation; the angle is obtuse; from it the 

 margin rounds downward and then upward in a single curve; the 

 lowermost part is finely serrate. 



Measurements. — Height of carpus, between distal angles, 18.S 

 mm. ; greatest height, 18.8 mm. ; greatest width, 12.8 mm. ; width on 

 upper margin, 12 mm. ; greatest width below the articulation with the 

 merus, 11.8 mm. 



Four specimens before me from the collection of the Academy of 

 Natural Sciences of Philadelphia belong to this species ; they are one 

 right and three left chelae and form part of the material referred by 

 Brown and Pilsbry to their G. scotti. (Paratype b) One left chela 

 is that figured on plate 22, fig. 2. 1 All are larger than the type ma- 

 terial described above, but so far as their characters are preserved 

 they agree in essentials with the type. (Paratype c) The right chela 

 (the largest specimen) its about 23 mm. long by 21.2 mm. wide, and 

 possesses a longer piece of the propodal finger than the other speci- 

 mens; the exposed cross section of the finger is oval. (Paratype d) 

 The shortest of the left chelae has a large part of the outer layer pre- 

 served on the infero-distal and inferior surface, where it is covered 

 with granules, arranged without regularity except for a row on the 

 outer surface parallel and close to the lower edge. This row is not 

 visible in my figure 14, plate 62. The longest of the left chelae 

 (Paratype e) is about 24 mm. by 19 mm., that is, considerably nar- 

 rower than (c).

Founded on two chelae, one with palm 20.6 mm. long, 16.5 mm. 

 wide, the other (without movable finger) with palm 9.4 mm. long, 

 5.5 mm. wide. 



Outer surface of palm arched, inner surface almost flat and with a 

 flat depression close to the lower margin and extending from the 

 fixed finger. The upper and lower margins are sharp, the former 

 bears 3 spinelike projections directed forward, the lowest spine ends
