XV. — Additions to the Crustacba and Ptcnogonida of thb 

 Bermudas. By A. E. Verrill. 



CRUSTACEA. 



The collection of Crustacea obtained by the Yale party in 1898 

 contains nearly all the species recorded from there by previous 

 writers, and many that are new to the fauna. Of marine Isopoda 

 and Amphipoda about 50 species were collected, but they have not 

 yet been carefully studied. Very few of them have been reported 

 from Bermuda. 



Lists of the Bermuda decapod. Crustacea have been published by 

 J. M. Jones,* A. Heilprin, and in the several Reports on the Zoology 

 of the Challenger Expedition, but they are all quite incomplete. 

 Mr. W. M. Rankinf has very recently published a more extensive 

 catalogue of the Bermuda Decapoda. His list contains 56 species 

 of this group. 



Our 1898 collection and those collected by J. M. Jones ; G. Brown 

 Goode ; C. Hartt Merriam ; F, V. Hamlin and others, now in the 

 Yale Museum, include about 20 species of Decapoda not contained 

 in Mr. Rankin's list, so that the total number now known is about 

 75. Nearly all of these are also West Indian species. 



To these may be added Geryon hicertus Miers, dredged in deep 

 water off Bermuda by the Challenger Exp. 



A number of the smaller and more difficult species have been sent 

 to Miss M. J. Rathbun of the U. S. National Museum for deter- 

 mination, and to her I am much indebted for aid of this kind, as 

 indicated under particular species. A few are still undetermined. 



* Mr. Jones sent to the Yale Museum, about 1877, a valuable collection of 

 Bermuda Crustacea collected by himself, during several years of residence there. 

 It contains a large example of the great land crab, Cardisoma Guanhum i. I was 

 informed that this species still occurs at Cooper's Island, but not elsewhere. 

 We had no opportunity to collect at that locality. 



t Annals New York Acad. Sci., xii, No. 12, pp. 521-548, May, 1900. This 

 list is based on the collections made by Prof. Bristol's parties in 1897-1898, but 

 it includes, also, those that were collected by Mr. G. Brown Goode, and most of 

 those obtained by the Challenger Expedition; some that have been enumerated 

 by Heilprin and others are omitted.
