Vitrea lucida seems now to have become a part of the fauna of the 

 Bermudas. 



In closing I take pleasure in acknowledging my indebtedness to 

 Mr. A. Gulick for his kind assistance in the determination of the 

 species named above, and to Dr. Pilsbry for the final determination 

 of Vitrea lucida and Zonitoides arboreus. 



NOTES. 



PENNSYLVANIAN SNAILS AND THE STATE ZOOLOGIST. In the 

 last Monthly Bulletin of the Division of Zoology of the Pennsyl- 

 vania State Department of Agriculture (Vol. II, no. 8), Prof. H. A. 

 Surface, the State Economic Zoologist, remarks (p. 245) : " Since 

 very little has been written concerning the molluscan life in Penn- 

 sylvania, we may at some future time prepare a Bulletin upon this 

 particular subject," etc., etc. As most of the common non-marine 

 mollusks of the Eastern States were described by Thomas Say from 

 Pennsylvanian examples, and there have been articles bearing on 

 our mollusks published at pretty short intervals for almost a century, 

 we had somehow gotten the idea that a good deal had been " written 

 concerning molluscan life in Pennsylvania." To be told that all that 

 conchologists have done upon Pennsylvanian mollusks in a hundred 

 years looks " very little " in the official eye of the State Zoologist, 

 is discouraging. He must be looking for something the size of the 

 Encyclopedia Britannica. We are on the watch for that promised 

 Bulletin. 



Califomian Nudibranchs. The publication of Dr. MacFarland's 

 preliminary account of the Doridida? (sens, latiss.) of Monterey Bay 

 (Proc. Biol. Soc., Wash., Feb., 1905), is an event of no little im- 

 portance to malacology. Out of twenty species, fifteen are new, 

 three belonging to new genera. Two of the new genotypes I had in 

 hand in 1901, and prepared descriptions; but I learned by corre- 

 spondence with Dr. MacFarland that he had them earlier, and had 

 studied their anatomy. I can, however, cite localities extending 

 their range far southward. Hopkinsia rosacea, MacF., was collected 

 by Miss V. Thomas at La Jolla, Aug. 3, 1901. The specimen was 

 apparently immature, being only about 12 mm. long, with only 5 

 branchial plumes. Its color was a brilliant crimson, the dorsal pro-
