INVERTEBRATE FAUNA OF LABRADOR. 277 



Glandula glutinans Mollek, Index Mollusc. Griinlandia?. 



Does not differ from specimens thus labelled, from Europe. Henley Harbor, six fath- 

 oms, sand. 



Cynthia pyriformis Rathke. 



This species was not uncommon in the Straits of Belle Isle. 



Cynthia condylomata n. sp. 



Test spherico-conical, surmounted by a spinulated apex ; it is a little higher than broad, 

 with transverse rows of lighter-colored, unequal, wart-like tubercles, which often terminate 

 in minute, blunt spinules, the larger ones stout and curved, with black tips. Apex of the 

 test high, rising up between the two orifices, into a square, truncate, corneous projection, 

 and terminating in five or six large spines. Incurrent and excurrent orifices, consisting of 

 four triangular depressed valves, beiug surrounded by a raised broad rim of crowded tuber- 

 cles, surmounted by spinules. Length, .50 inch. A still larger specimen, over an inch in 

 length, from the Banks of Newfoundland, is in the Museum of the Essex Institute. 



This species may be easily recognized by its conical form, with circles of large wart-like 

 tubercles, and the steeple-like corneous apex, truncated at tip, and armed with acute, short 

 thick spinules. 



Caribou Island, eight fathoms, on Nullipores. 



Cynthia echinata (Linn.) 

 Dredged at a depth of fifty fathoms in Chateau Bay. 



Cynthia placenta n. sp. 



Test broad, expanded, much flattened, very emarginate, about five times as broad as 

 high, with the thin edge uneven, revolute ; surface granulated, though the scales are flat- 

 tened. Anal and branchial orifices much alike, of equal height, and as distant from each 

 other as the thickness of the test, which is half an inch in diameter. 



One specimen covered with sand was larger and more roughened about the orifices than 

 the other specimen, which was smooth and naked. 



Dredged in the Straits of Belle Isle, forty fathoms, hard bottom ; Henley Harbor, ten to 

 twenty fathoms, sandy ; Cateau Harbor, Long Island, fifteen fathoms, sandy. It is also 

 common in the Bay of Fundy. 



Felonaia arenifera Sumps. 

 This occurred in fifteen fathoms, sand, at Salmon Bay, in the Straits of Belle Isle. 



Boltenia Bolteni Linn. 



Bohenia oviformis Sav. Pack. Can. Nat. 1863. 



Comparison with specimens from Greenland shows that this common species is found 

 along our northeastern coast from the Bay of Fundy to Greenland.
