II. — Additions to the Fauna of the Behmudas from the 

 Yale Expedition of 1901, avith Notes on Other Species. 



By a. E. Verrill. 



The following additions to the fauna of the Bermudas are due 

 almost entirely to the large collections made in the spring of 1901, 

 by Mr. A. H. Verrill, who was there from March 7th to May 9th, 

 and the writer, who took part in the work from April loth to May 

 9th. Dr. W. G. Van Name joined us during the latter part of the 

 time, but he worked chiefly on the Tunicata, which are not included 

 in this article. 



About To species of insects and 25 species of spiders were also 

 obtained. Many of these were not before knowni from Bermuda, 

 but they will be treated in subsequent articles. The numerous 

 Isopoda and Amphipoda, and most of the Annelida, also remain to 

 be studied, as w^ell as man}- of the smaller shells, among which there 

 are probably many additions to the fauna. There are also some 

 additional land shells, Myriapoda, earthworms, etc. 



I have added notes on some of the rarer or less known species, 

 of those previously recorded,* where such information seemed partic- 

 ularly desirable, for the benefit of future students. 



That so many species of comparatively large and conspicuous 

 marine animals could be added in a few weeks to the fauna of a 

 locality, where so many previous collections have been made, may 

 seem strange. This is due, however, partly to a very careful scru- 

 tiny of the hiding places of those foi-ms that depend upon conceal- 

 ment for their safety, partly upon the fact that localities were visited 

 where we did not collect in 1898, in which certain species seem 

 to be localized, and perhaps, in some cases, upon the earlier season 

 of the year (March), Avhen some of the new forms came into shallow 

 water to spawn. 



The illustrations are mostly from colored drawings, made from 

 life, by Mr. A. H. Verrill. Others are from photographs made by 

 him, either from living or freshly killed specimens. It is unfortu- 

 nate that the colored figures could not now be reproduced in colors 

 by the Academy, for in these groups of soft-bodied animals the 

 colors are often highly characteristic, as well as beautiful. 



The marine invertebrate fauna of the Bermudas, now known, 

 includes about 900 species. The known fishes are about 200. 



* Species previously recorded are in italic type. Those now first recorded 

 (so far as known) are in black-face tyjie.
