Se\eral cithers occur occasionally <>i- sporadically on lliis coast, 

 beino- carried northward l>y theCJulf Stream, or l>y shipping, lul 

 fail to become naturalized so far north, owino- to the cold of winter. 



It is evident, t heret'ore, that the llcrmuda 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 au'ree with the Antho/oa, Mollnsca, Kchino- 

 derms. Fishes, etc. 



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

 as now known, peculiar 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: 



iSesarm</ Ku-ordi, var. terrestris, PetroUsthes arinntxs, var. palli- 



nov. dus, nov. 



Snpanopeus Serbstii,va,T.minax, Mimida Beanii, sj>. nov. 



nov. Clibanarius Verrillii Rathbun. 



fc. bermudensis, var. scidptus, nov. Clibanarius hebes, sp. nov. 



widely distributed free-swirnming forms 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 coast 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- 

 ivi-tly 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, biit that is largely due to the fact that the West Indian Isopods have 

 not been very thoroughly collected and studied. 



I>r. I'.. \V. Kunkel has found, among the 45 species of Bermuda Amphipods, 

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

 Aiii]ihi]iods aiv little known. Twenty species, so i'ar as now known, are peculiar 

 to Bermuda, (Science, vol. xxvii, p. 4S9, 1908.) 



The Bermuda Eutomostr.u-a have not been much studied. Among the para- 

 sitie sjiei-it-s Mr. (.'lias. P. Wilson lias recently identified the following : AV.s/ynr-x 

 ix Dana : I'timlm-ns ('runcliii Leach (from shark) JsfjK'ii/ilttlH'irHx (7/s- 

 s 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.
