obsolete, being replaced by bliiut promiiieuces. There is a blimt tooth

 of mauus coarsely and sparingly tuberculate. In specimens larger than 

 the one photographed (Plate XVIII), the lateral spine is proportionally 

 shorter and the chelipeds much heavier. 



Size. — Adult males measure 4g and 4^ inches in width, with a length 

 of 2i inches. An adult female is 4^e inches wide and 2 inches long. 



Measurements of Callinectes tumidus.

CALLINECTES TUMIDUS GLADIATOR, Benedict. 



CaUhievles titmidiis, var. gladiator, Benedict, Proc. U. S. Nat. Mus., XVI, 1893, 

 p. 537. 



Distinguished from G. tumidus by its longer lateral spine and less con- 

 vex carapace. The abdominal appendages are curved as in typical 

 C. tumidus, and the front and lateral teeth correspond to that species. 



Type. — Small male from Beyah River, Elmiua, Ashantee, Africa, 

 U. S. Eclipse Expedition, 1889 (No. 14879, U.S.N.M.).

iThe brief description given by A. Milne-Edwards corresponds to the specimens 

 which I have referred to this species. An individual labeled " Callinectes bocourti, 

 A. M. Edwards, Belize, Honduras," recently received from the museum at Paris, is an 

 undoubted C. danw. I am loath, however, to make C. bocourti a synonym of C. dana' 

 tmtil I am assured that the specimen was correctly labeled, in which, case the species 

 here called C. bocourti must receive a new name.
