the Shells of Maine. 329 



Genus Terebratula. Brug. 



T. caput-serpentis, Lin. Pelagic. Diminutive specimens 

 of this interesting shell are ibund rather plentifully in the 

 stomachs of haddock taken in Casco Bay. The largest and 

 finest specimens I have seen were dredged by Captain Walden 

 near the Fox Islands. A specimen now lies before me 1.4 

 inch in height, 1.1 inch in width. It inhabits very deep water. 

 A fisherman brought me a stone which he fished up with a 

 cod hook, in (he says) 75 fathoms of water ! It was covered 

 with fine specimens of this shell. 



T. psittacea, Gmelin. Pelagic. I am not aware that this 

 species occurs in the waters of Maine. In the summer of 1841, 

 a fisherman gave me twenty-seven specimens which he took 

 from the stomachs of sand-dahs in the Gulf of St. Law- 

 rence. A specimen now before me is .8 inch in height, .7 inch 

 in length and .5 inch in breadth. This is the largest ; most of 

 them were much smaller. 



Genus Chiton. Lin. 



C IcBvigatus, Flem. (^C.fulminaius, Couth.) Small speci- 

 mens of this species are found, sparingly, in fishes' stom- 

 achs caught in Casco Bay. Dr. Ray has found it on the rocks 

 at Eastport, during spring tides, above low-water mark. A 

 specimen of whicii, now before me, is 1.2 inch in length. 

 Never having detected it here, (at Portland) in a similar situ- 

 ation, I infer that its more congenial habitat is further north. 

 Having had an opportunity of comparing it with a specimen 

 of C. IfKvigatus, in the cabinet of Dr. Gould, of Boston, from 

 Sweden, wjiere it is said to be common, I have no doubt of 

 their identity. 



C. ruber, Lowe. Pelagic. Taken from fishes' stomachs 

 caught in Casco Bay. Rare. 



C. (tlljusj Mont. Pelagic. This, with the following spe- 

 cies, is found in company with the preceding. Rare. 



C. emersouli, Couth. 



C. mcndicarius, Migh. Pelagic. The only specimen of
