1,700 to 2,000 feet. The form named cinereus by Reibisch was ob- 

 tained at Iguana Cove, Albemarle Island, and the variety acutus 

 Reibisch, at a height of 3,000 feet, near Tagus Cove, Aloemarle 

 Island. The species is usually found under flat pieces of rock, and 

 a large proportion of the specimens are dead." (Dall, 1. c., p. 91.) 

 Notes on new localities for known species follow : 

 B. DUNCANUS Ball (p. 114). Specimens were taken on Duncan 

 Island. "As in previous cases, all the specimens were dead, and 

 those collected were not quite mature, as the parietal denticle had 

 appeared in none of them. The species is probably extinct." 



B. ESCHARIFERUS Sowerby (p. 108). Chatham and Barrington 

 Islands, Snodgrass and Heller. This species had not been found at 

 Barrington previously. 



B. TANNERI Dall (p. 113). Tagus Cove, Albemarle Island (Snod- 

 grass and Heller). This species was previously known from Inde- 

 fatigable Island. The present specimens are not fully grown, and 

 do not show the broadly reflected lip. 



B. INDEFATIGABILIS Dall. (Vol. xi, p. 123, pi. 24, f. 49.) 



This name is proposed for the hitherto nameless new species fig- 

 ured by Dall in 1896.

Genus NEOPETR.EUS Martens (Vol. xi. p. 163). 

 The typical forms of this genus have very characteristic apical 

 sculpture, but in some species referred here, this sculpture is want- 

 ing, the apex being smooth. A knowledge of the soft anatomy is
