NO. 1316. SOME CUBAN CRUSTACEANS— HAY. 435 



II. CALLINECTES SAPIDUS ACUTIDENS Rathbun. 



Five specimens as follows: Mouth of Yuimiri" (2), Pinar del Rio (1 

 large male), San Juan (1 female), unknown locality (1 small male). 



12. EPILOBOCERA CUBENSIS Stimpson. 



A small series of two males, one female, and one young from Ashton 

 and one young from Modesta represent this species. 



13. GONIOPSIS CRUENTATA (Latreille.) 



Two specimens from the mouth of the Yumuri River, a male and a 

 female. The male is the larger and more brilliantly colored. The 

 female carries a large mass of eggs. 



14. UCIDES CORDATUS (Linnaeus). 



Two specimens (male and female) from the mouth of the Yumuri 

 River. The male has recently suffered the loss of two of his legs and 

 is beginning to reproduce them. They now consist of buds about 

 one-half an inch long in which five segments can be distinguished, but 

 the last three are bound down tightl}^ against the other two and 

 inclosed with them in a chitinous envelope. If the limb is removed 

 from this capsule and extended it is about 25 millimeters in length. 



To what extent this method of reproduction obtains among the 

 Crustacea I am unable to say, but I have observed it in several species 

 of Brachyurans. In the Macrura, on the other hand, in the few cases 

 which I have observed, the new limb appears as a bud in which the 

 segments are extended as in the fully developed appendage. 



"The following note has been supplied by Dr. Eigenmann: El Sumidero is a river 

 running in part underground west of Pinar del Rio. The Yumuri River is a stream 

 emptying into the ocean at Matanzas.
