NO. 1210. ,S' YXOPSIS OF NOR TH AMERICAN TELLINID.E—DALL. 313 



probablj- that alluded to hj Bertin in 1878, as received from Florida 

 by Petit, under the name of Tellma unifasciatn, and which he refers 

 to xingidus. 



TELLINA (ANGULUS) COLORATA new species. 

 (Plate II, ris;. 9.) 



Shell small, compressed, subtriangular, suffused with rose color or 

 pale yellow, sometimes showing- minute, subtranslucent, subradial 

 vermiculations, sculpture of faint incremental lines, the posterior end 

 shorter, rather blunt, slightly flexuous; hinge with the lateral very 

 short and close to the cardinals; pallial sinus su])triangular, the apex 

 rising considerably above the level of the posterior adductor, the ante- 

 rior end not reaching the anterior adductor scar, the lower portion 

 wholly confluent; there is an obscure posterior ray. Lon. 13.5, alt. 

 9.5, diam. -1 mm. 



Tij2)es. — No. 1:2865, U.S.N.M., from the island of Guadeloupe, West 

 Indies. 



TELLINA (ANGULUS) TEXANA new species. 



Shell small, thin, sharply flexed, varj^ing from ivory white, through 

 j^ellowish, to pale pinkish brown; subequivalve, inequilateral, the 

 anterior end longer, moderately convex; epidermis verv thin, silky, 

 with an iridescent play of colors upon it when fre.sh; beaks rather high 

 and pointed, anterior dorsal margin subarcuate, declining into the 

 evenly rounded anterior end; posterior end short, rapidly declining, 

 subtruncate or obtusely pointed, markedly flexed to the right; surface 

 near the beaks nearly smooth, toward the margin linel^y concentricallv 

 grooved, the grooves becoming more crowded, until in some cases 

 the interspaces resemble minute close-set threads; there are also flne, 

 almost microscopic, radial stria? and the usual obtuse ridge at the pos- 

 terior angle; hinge normal, adjacent lateral strong; pallial sinus long, 

 not precisely similar in Ijoth valves, but reaching the anterior adductor 

 scar in neither; the valves, if the epidermis is lost, do not appear 

 polished; lon. 14, alt. 8.2, diam. 4.6 mm. 



Ilahitat. — Various localities in Corpus Christi Ba3% Texas, Singlev, 

 and Charlotte Harbor, Florida, in 3 or 4 feet of water, over a sandy 

 bottom. Dall. 



From T. {AncjiduH) tenella Verrill, which is perhaps its nearest ally, 

 it differs in outline, has more arcuate dorsal margins, a straighter base, 

 and more attenuated posterior end. That species is grooved over the 

 whole disk and has the grooving more sharp and regular. 



Type.—^o. 125539, U.S.N.M.
