All the specimens from the Gulf of Siam agree most closely with Hanley's 

 figure (pi. 58, fig. 96). 



Note. When Ed. v. Martens records (Malakozoolog. Blätter, vol.21, 1873, 

 p. 176) that Tellina (Scissula) virgo, Hani., was taken "Am Eingang des Golfs von 

 Siam, 8° 29' Nordbreite, 16 Faden," it is certainly due to erroneous determination. 

 According to Dall (Synopsis of the family Tellinidæ, 1900, p. 304) the species occurs 

 from "Gulf of California, la Paz, to Chiriqui." Also Hanley's original specimens are 

 recorded from Chiriqui, West Columbia.
