t06 MK. J. R. HENDERSON — A CONTRIBUTION 



The largest specimen, a female, is covered by a sponge; its carapace is 19*5 mm. loug 

 unci 19 mm. in breadth.

Silavaturai Par, three males {Thurston). 



These certainly belong to the species as figured and described by De Man. One 

 specimen is covered by a sponge ; the largest is only 9 mm. long.

Muttuwartu Par, four specimens (one covered by a sponge) ; Silavaturai Par, two 

 specimens {Thurston). 



I refer these with some uncertainty to this species, as the antero-lateral margin of 

 the carapace is scarcely so long as represented by Hilgendorf ; otherwise they agree 

 well with it, and are identical with specimens from Mauritius named C. pentagonalis 

 in the British Museum. The Silavaturai examples have a rudimentary tooth or almost 

 an indentation on the lateral margin of the carapace, between the antero-lateral angle 

 and the tootli which marks the cervical groove. A trace of this may also be seen in the 

 Muttuwartu examples, but it is not represented by Hilgendorf. A more prominent 

 tooth is seen in the same position in C. tomentosa, Heller (= C. canallculata, Stoa., fide 

 De Man), and as the latter species otherwise resembles C. pentagonalis perhaps the two 

 are not distinct.

Tuticorin, two females with ova {Thurston). 



The carapace is smooth and polished, very sparingly pubescent, and regularly convex, 

 both from side to side and from end to end. The surface is a little uneven, and the 

 branchio-cardiac and cervical grooves are well marked, the latter indenting the lateral
