TELLINA (MERISCA) CRYSTALLINA Wood, 1815. 



Lower California to Panama; also Atlantic coast. The specimens 

 from the two oceans are absolutely similar, and differ no more than 

 individuals from either sea among themselves. 



TELLINA (ELLIPTOTELLINA) PACIFICA Dall, 1900. 



Panama Bay, and proba))ly northward. This is the Pacific analogue 

 of TeU'ma\E.) americana Dall, which is differently sculptured. From 

 the figures Tellina clathrata Bertin, 1878, is a third recent species of 

 Elliptotelllna^ but appears to be smoother and to have a much longer 

 and more confluent sinus than either of the American species. 



TELLINA (PHYLLODINA) PRISTIPHORA Dall, 1900. 



Lower California, near La Paz, in 26 fathoms. 



TELLINA (EURYTELLINA) RUBESCENS Hanley, 1844. 



Margarita Bay, Lower California, to Panama. This is the Pacific 

 coast analogue of Tellina angulosa Gmelin, which is very similar, but 

 distinguishable. TeUiiia simulans C. B. Adams, 1852, and Tellina 

 punicea Carpenter, 185T, not Born, 1778, are synonymous. 



TELLINA (SCROBICULINA) VIRIDOTINCTA Carpenter, 1855. 



Lower California to Panama. 



TELLINA (SCROBICULINA) OCHRACEA Carpenter, 1864. 



Caj^e St. Lucas to the Gulf of California. 



Extremely similar, except in color, to the preceding species. 



TELLINA (QUADRANS) COGNATA C. B. Adams, 1852. 



Panamic fauna; Guatemala. 



This is Macoma cognata of Adams and Psammohia casta (Deshayes) 

 Reeve, 1857, but not Tellina casta Hanley, 1811. 



TELLINA (TELLINIDES) BRODERIPII Deshayes, 1857. 



Cape St. Lucas to Panama; Gulf of California. 



This is Tellina purpurea Broderip and Sowerby, 1829, but not of 

 Dillwyn, 1817; Tellina purpura^cens Hanley, 1816, ]>ut not of Gmelin, 

 1792. 



TELLINA (MOERELLA) SALMONEA Carpenter, 1864. 



Aleutian Islands and southern part of Bering Sea, southward to the 

 Santa Byir' ara Islands, California. 



Th's is a widely distributed species, variable in color, but very con-
