INVERTEBRATE FAUNA OF LABRADOR. 287 



Bela pyrimidalis Shuts. 



Fusus rufus Gould. 



This species is found along the whole coast. Taken in thirty fathoms, at Square Island. 



Bela cancellata Mighx. 



Not uncommon at Square Island in thirty fathoms. 



We should scarcely unite B. Pingelii (Beck) from Greenland, with this form. It differs 

 in the long and slender, scarcely turreted, less convex whorls ; the costal and revolving 

 lines are fainter, and the last are more numerous ; the canal is slenderer and more pointed. 

 Eeeve's Fusus rugulahis Icon. Conch, is perhaps a synonym of B. Pingelii, though stated by 

 Morch to be identical with B. exarata. 



Bela violaeea Stimps. 



Common along the whole coast. Dredged at Square Island, in thirty fathoms, on a shelly 

 bottom. 



Bela borealis. 



Pleuroloma borealis Reeve, 1. c. f. 277. Defrancia livida Moll, (non Linn.) 



This species occurred but rarely. It was found at Square Island in thirty fathoms ; at 

 Sandwich Bay in four fathoms.

A fine specimen of this species, but belonging to a rather more elongated type than 

 usual, comes from the Banks of Newfoundland, and is in the collection of Mr. C. B. Fuller of 

 Portland, who kindly loaned us two specimens for illustration. 



It did not occur to us in a living state on the coast of Labrador, though it will doubtless 

 be found there on more careful search. 



A fossil specimen occurred at Pitts Arm, Chateau Bay, with nearly all the outer coating 

 of shell off. It is thick and stout. (PI. vii. fig. 5 a.) The large single spiral rib is very promi- 

 nent, while midway between it and the suture are two ribs of half the size. 



I have also received a much thinner shell from the Leda clays of Montreal, kindly sent 

 by Dr. J. W. Dawson, associated with Trichoiropis borealis ; also from Negrotown Point at 

 Carleton, opposite St. John, N. B., collected by Messrs. Mathews and Hartt. 



From Canal Street, Portland, specimens collected by Mr. C. B. Fuller are unusually ventri- 

 cose, more heavily plicated with large costae. increasing in size nearer the suture than 

 usual, and with a large raised revolving line. 



This very rugose form [PI. vii. fig. 5] also occurred fossil at Caribou Island. Young spec- 

 imens collected at Portland by Mr. Fuller, however, conform more to the slender type, and 

 agree in all respects with Lyell's figure in the Transactions of the Geological Society.
