E. purpurea, which is probably the same as Ervilia 

 scaliola of Issel, does not appear to have been described. 

 There are specimens in the British Museum from the Dahlac 

 Archipelago, Red Sea, named by Deshayes Ervilia purpurea, 

 but he did not, as far as I can ascertain, publish any descrip- 

 tion of them. They are elongate, inequilateral, narrower 

 behind than in front, sharply rounded at both ends, brownish- 

 purple, with two or three whitish rays, two down the middle 

 of the valves, and sometimes a third at the posterior end. 

 Valves moderately strong, sculptured with fine stride of 

 growth. Interior pui-plish-brown, obscurely rayed with 

 white, especially at the ventral margin. Muscular scars 

 moderately large, and the pallial sinus extending yV of the 

 length of the shell from the posterior end. 



Length 12*5 mm., height 7, diani. 4*25. 



The shells described by Issel were very small, only 5 mm. 

 in length, and were apparently of an uniform, pale-rose tint, 

 without any colour rays. Their form, however, was exactly 

 the same as that of the larger shells from the Dahlac Islands,
