altogether concealed. The gastric and cardiac regions are smooth, 

 but laterally the tubercles mentioned in the original description 

 can be made out; apart from these the upper surface appears to 

 be without evident sculpture. The side-walls are finely granular 

 and seem to show traces of a rather deep sculpture, the grooves 

 apparently forming a pattern somewhat similar to those found in 

 Dotilla myctiroides ; it is, however, difficult to be certain about this 

 point owing to the poor condition of the specimen. 



The epistome is very broad and exceptionally short. The 

 ])enultimate segment of the second maxilliped is broader and the 



last segment more parallel-sided and 

 proportionately longer and narrower 

 than in other species of Scopimera. 

 The third maxillipeds are also unusu- 

 ally broad and differ from normal spe- 

 cies of the genus in having the ischium 

 shorter than the merus (text-fig. 8). 

 The ischium has a rather thick patch 

 of hairs near its postero-lateral angle 

 and the suture between it and the 

 merus is nearly transverse. The me-

Third maxilliped. ym . {^ jg ^g,-y little narrowed distally 



and is angled antero-internally. The 

 anterior margin is reflected upwards, a short ridge runs backwards 

 from the carpal articulation and there is a deep groove parallel 

 with the lateral margin. 



The chelipeds are about 15 mm. in length. There is a large 

 tympanum on the inner face of the merus, subdivided longitudin- 

 ally by a ridge as in Roux's S. kochi. The tympanum on the 

 outer face is without this ridge and is a little smaller, though broad 

 and in length about half that of the segment. Except for the 

 tympana the entire segment is finely granular. A. Milne-Edwards 

 in his description says " avant-bras allonge et arme d'une epine a 

 son angle interne." This statement refers to the male. In the 

 female there is no tooth, but the inner margin is concave and sharp- 

 edged anteriorly and is obtusely angled in front of its middle point : 

 in this respect there is a great difference between 5. inflata and 

 S. glohosa. The carpus of the female is not elongate ; its upper 

 surface is about one and a half times as long as broad and is closely 

 covered with granules. The chela is about 8 mm. in length and its 

 greatest height, which is about twice that at the articulation of the 

 carpus, is 37 mm. The whole palm is strongly compressed and the 

 entire outer surface is conspicuously granular. The upper border 

 is not carinate. On the outer side near the lower border there is a 

 sharply defined beaded carina which extends from the proximal 

 end to the distal third of the fixed finger ; on the inner side a simi- 

 lar, but even more strongly marked, carina reaches from the carpal 

 articulation to the middle of the inner .side of the fixed finger.
