The most important record from Dog's Bay is undoubtedly the 

 occurrence oi Lepton Sykesii, Chaster, in the shore drift. For original des- 

 cription see Ann. and Mag. Nat. Hist, for March, 1895, p. 248 ; and Journal 

 of Malacology, June, 1895, p. 36, for further notes by J. T. Marshall. Both 

 record it only from Guernsey. 



Mr. Nichols took Modiolaria marmorata, Cardhun tiojvegicum, Venus casina, 

 and Chiton 7?iarginatus at Gleninagh — the latter species being also found 

 by Miss Kelsall at Aranmore. I found Rissoa violacea and R. parva in 

 abundance near Kilronan, and under stones at low water near Killeany, 

 B. undatum var. littoralis occurred — a pretty little form exactly agreeing 

 with West of Scotland examples. 



The late Dr. Alcock gives a list of about fifty species from Dog's Bay in 

 Trans. Lit. and Phil. Soc. Manchester, 1866, including several species not 

 taken by us, but the following catalogue contains many additional species, 

 and amply indicates the rich field which exists here for some systematic 

 dredging with modern appliances.
