American Tertiary Sheees 



17 



Our specimen is mainly in form of a east, from the City Quarry 

 near Wilmington, N. C, found among many other beautiful 

 molluscan remains, echinoderms and branchipods. 



We take great pleasure in styling this the Dall Pecchiolia not 

 only on account of the great and valuable Tertiary work of this 

 author, but especially on account of his early extensive and pains- 

 taking work on this branch of Pelecypoda. 



Type. — Deposited by Harris in Museum at Cornell. 



Meretrix angelinae n. sp., Pi. 2. Figs. 12, 13. 



Specific characterization. — Shell large (65x54x15mm) and 

 oblong, as indicated by the figures ; anterior somewhat extended 

 as in Cornelli but posterior not with broad circular sweep of con- 

 centric lines, but with more or less of a rectilinear truncation ; pal- 

 lial sinus small, V-shaped ; anterior muscular scar sharply defined, 

 posterior scarcely visible ; a few obscure radiating ridges intern- 

 ally and a few radiating lines. 



This large species, (figures somewhat less than life size,) is 

 found in the state of casts and impressions in sandy ironstone 

 fragments gathered by A. C. Veatch along the Angelina River, 

 Angelina County, Texas, 2 miles above Marion. 



It seems very different from anything with which we are ac- 

 quainted in the lower Eocene beds, and is here associated with an 

 abundance of A nomia, (also Plica tula filameatosa, Ost? ea var. ver- 

 milla, Splicerella bulla and anteprodu eta,) reminding one strongly 

 of the St. Maurice beds of Louisiana ; also a small, smooth Pecten ; 

 but most telling among its associates are Haminea grandis, Pleur- 

 otoma creno-strinaia Heilp. , of Jackson age ; but one of the most 

 abundant species is Rimella oi.texana, a St. Maurice form. A 

 Fusoficula and an unusually large Tomatina are among the un- 

 described associates. (See below.)
