20 MARINE INTERTEBRATA OF GRAND MAN AN. 



A. TENELLA, St., 1. c, 228. Ill thirty-five f., off Gr. Duck Island. 



A. GEOMETRiCA, St., 1. c, 229. Ill forty £, off Long Island. 



Glandula fibrosa, St., 1. c, 230. Dredged in considerable numbers on muddy 

 bottoms in the coralline zone. They appear like hard balls of mud, about the size 

 of an ounce bullet. 



G. MOLLIS, St., 1. c, 230. In ten f sand, off Cheney's Head. 



Cynthia ptriformis, Eathke. This species I have identified by European ex- 

 amples sent me by M. Sars. They are perfectly the same. It is one of the most 

 beautiful marine productions found in this region, having, in its hard velvety sur- 

 face, and bright pink blush, precisely the aspect of a blood-peach. In fict, it is 

 called sea-peach by the inhabitants. Some of my specimens are three inches in 

 length. It lives in clear water on rocky bottoms among nullipores, sometimes at 

 low-water mark, but usually in four or five fathoms. 



C. ECHiNATA, St. On rocky bottoms. 



BoLTENiA RUBRA, St., 1. c, 232. One specimen only of this species was found, on 

 weedy rocks, in four fathoms. 



B. reniformis (?), Macleay. This species is very distinct from the preceding, 

 being uniformly of a fine yellowish-white color, with a smooth velvety surface. It 

 inhabits rocks in deep water, never occurring in less than fourteen fathoms. I am 

 far from certain that it can be referred to B. reniformis, but approaches that species 

 more than any of the others mentioned by Macleay in his memoir. 



BRACIIIOPODA. 



Terebratula SEPTENTRlONALis, Couth. Common. 



LAMELLIBRANCHIATA. 



Anomia ephippium, L. Roots of Xamna nee; very small. 



A. aculeata, Gm. Rather common in deep water. 



Pecten Magellanicus, Lam. This species was once taken abundantly in this 

 localitj', and used by the inhabitants as food, but seems now rapidly decreasing in 

 numbers. It is now rarely seen alive, though beds of dead shells are often met 

 with at depths of 20 and 30 iathoms, which afford excellent shelter to many marine 

 animals. A few small living specimens were dredged in 10 f. sand, near Duck 

 Island outer ledge. 



P. ISLANDICTTS, Miill. Distorted specimens are occasionally found under stones 

 at low water, but it usually occurs on shelly bottoms, in 25 to 40 f 



NucuLA PROXiMA, Say. In 4 £ sand, off Duck Island weir. 



N. TENUIS, Turt. In from 4 to 40 f mud.. 



N. DELPniNODONTA, Migh. 25 f. mud, on the Hake Ground. 



Leda thracleformis, St., N. E. Test. Moll., 9. In 25 f mud, off Duck Island. 



L. SAPOTiLLA, St. . 10 f, Welch Pool. 



L. MTALis, St. 20 f mud, off Duck Island. 



L. LiMATULA, St. G f mud.
