A. E. Verrill — Decapod Crustacea of Bermuda. 453 



Two species, CaUinectes sapidns, Enpanopeus HerlMli and its 

 var. obesus, range northward to southern New England, as per- 

 manent residents. 



Several others occur occasionally or sporadically on this coast, 

 being cari-ied nortiiward by the Gulf Stream, or by ship{)ing, but 

 fail to become natui'alized so far north, owing to the cold of winter. 



It is evident, therefore, that the Bermuda Decapod Crustacean 

 fauna is an offshoot or colony from the West Indian fauna, with 

 only a slight admixture of species from other regions. In this 

 respect the Crustacea agree with the Anthozoa, Mollusca, Echino- 

 derms. Fishes, etc. 



Of the total number, only seven species and subspecies are, so far 

 as now known, })eculiar to the Bermudas. These are all recently 

 described forms and no doubt most of them will soon be discovered, 

 also, in the West Indies. They are as follows: — 



)Sesarmif. Ricordi, var. terrestris, Petrollsthes armatus, vai-. ixtlU- 



nov. dus, nov. 



Eupanopeus IIerhstii,\diV.minax, Mimida JBeanii, sp. nov. 



nov. Ciihanarius VerrilUi Rathbun. 



E. bermiidensis, var. sculptus, nov. Clibanarius hebes, sp. nov. 



widely distributed free-swimming fdrms which extend their range even to the 

 Indian and Pacific Oceans ; 3 have been found on the west coast of Africa; 2 on 

 the southern coasts of Europe ; 9 species reach the Carolina coasts ; 1 ranges to 

 New England ; 3 to the Pacific eoas.t of North America. 



Of the total number, 4 have not yet been found in the W. Indies, but one of 

 these is a new species, recently discovered, and another is, perhaps, not cor- 

 rectly named. 



The marine Isopods, which have been well worked up by Miss Richardson, 

 afford a much larger proportion of species peculiar to Bermuda, so far as now 

 known, but that is largely due to the fact that the West Indian Isopods have 

 not been very thoroughly collected and studied. 



Dr. B. W. Kunkel has found, among the 45 species of Bermuda Amjahipods, 

 a considerable proportion, 20-21, of Mediterranean species, but the West Indian 

 Amphipods are little known. Twenty species, so far as now known, are peculiar 

 to Bermuda, (Science, vol. xxvii, p. 489, 1908.) 



The Bermuda Entomostraca have not been much stiidied. Among the para- 

 sitic species Mr. Chas. P. Wilson has recently identified the following : Nesipus 

 cu rf icaiidis Jiana, ; Pandarus Crayichii Leach (from shark) ; Lrpeophtheirus dis- 

 f^imiilafus Wilson (stomach of hamlet grouper). 



In the spring of 1898 we found an undetermined Ostracode Crustacean abun- 

 dant in the rain-water tanks at Bailey Bay. 



The three species of Stomatopoda are all West Indian forms.
