EUGLANDINA. 179 



Venezuela: mountains near Coro (Oapt. Foster). 



This species resembles E. rosea parallela in its solid tex- 

 ture, and E. liebmanni in the coarse sculpture. In the fine 

 spiral sculpture and the embryonic whorls it differs widely 

 from both, and is related to E. truncata Grmel. (subvaricosa 

 Alb.). From the latter it differs by the solid texture, coarser 

 sculpture, narrower form and much less concave columella. 

 Based upon four specimens, taken Aug. 14, 1864. The col- 

 lector notes that the upper tentacles are darker than the other 

 parts; the back is dark ash color, the sides and foot almost 

 white. Named in honor of Robert Swift, whose rich collec- 

 tion of South American and Antillean mollusks was devised 

 by him to the Academy.

Colombia: Ocana (Wallis). 



The names proposed by Tryon and by von Martens were 

 both based solely upon the full account given by Strebel, who, 

 in the absence of material for comparison, identified the 

 Colombian form with aurata. Tryon carelessly gave the local- 

 ity "Mexico." The spiral sculpture seems to resemble the 

 Mexican rather than other South American species.

 what thickened at the edge. Length 51, diam. 21, aperture
