Serpulites Murrayi, S.N. 



Tube cylindrical, slightly curved in the part preserved, smooth, 

 with indications of a thin shell. Diameter of largest specimen 14 

 millimetres at the larger end and 11 millimetres at the smaller 

 end. Length 10 centimetres. Several fragments of .^mailer 

 size may belong to young individuals or to the terminal portions 

 of adults. 



This tubular cast, destitute as it is of the outer shell, can 

 scarcely be referred with certainty to the serpulae. It might 

 have belonged to a mollusk ; but in the mean time may be pro- 

 visionally referred to Serpulites. The specimens are from Dr. 

 Bell's collection at Port-au-Port. Dedicated to Alex. Murray, 

 C.M.G., F.G.S.; Director of the Geological Survey of Newfound- 

 land. 



MaCROCHEILUS TeRRANOVICUS, S.N. 



Shell conical in form, with five volutions strongly shouldered 

 and with deep suture, each turn becoming one-third smaller 

 than that below. Lower volutions each with 12 to 13 vertical 

 ribs, more strongly marked at the suture and fading below. 

 Aperture ovate, rounded in front, slightly angled behind. Um- 

 bilicus small. Length 8 millimetres. 



Very abundant in some spe,cimens in Dr. Bell's collections 

 from St. George's Bay. A little shell found very abundantly at 

 Pugwash, Nova Scotia, and referred in Acadian Geology (p. 309) 

 to the genus Turbo, probably belongs this genus. It dificrs from 

 the present species in having as many as twenty folds in the 

 suture. 



Pteronites Gayensis (var. ornatus). 



General form of shell similar to that of Ft. Gayensis (Acadian 

 Geology p. 301), but differs in its somewhat larger size and in 

 the ornamentation of the whole shell with delicate raised concen- 

 tric lines instead of obscure rounded wrinkles. The left beak is 

 considerably more prominent than the right, the hinge line slightly 

 curved inward, and the ridge along it well marked. Length of 

 shell one centimetre. Port-au-Port, Newfoundland, collections of 

 Dr. Bell and Mr. Paterson. 



I should have been disposed to regard this shell as a distinct 

 species, but for the fact that there is a probability that the Gay's 

 River specimens have lost their finer ornamentation, and that
