also obliquely ridged. 

 :2o. Turricula mucronata Swainson. Reeve, 1. c, pi. 17, 

 %• 125. 



This species, which appears to be rather scarce, was 

 found buried in sand inside the reefs, in shallow water, at 

 ^j the Society and PaWotu Islands. 



It is shaped very much like T. concentrica, and has a 

 similar wide basal band, but may be readily distinguished by 

 the double row of sharp tubercles and granulated base. 



The animal has the upper surface of the foot a rich 

 reddish-brown, irregularly dotted with yellow, and the creep- 

 ing disk cinereous. Siphon dusky with yellow dots. 



121. Turricula millecostata Swainson. Reeve, 1. c, pi. 

 xxxvi., fig. 301. 



Of this very rare species we have found only four dead 

 examples on the outer beach at Anaa, PaAmotu Islands, the ^y 

 same locality of Swainson's type specimens. ' 



The color appears to be somewhat variable : one speci- 

 men is dark chestnut with a white apex, as mentioned by 

 Reeve, and two are orange-yellow, with two broad interrupted 

 ferruginous bands. The other is reddish-chestnut, faintly 

 mottled with orange-yellow, with two remote transverse lines 

 of the latter color. The transverse impressed striae extends 

 over the whole surface, and the base is conspicuously 

 granulated. 



Mr. Reeve's figure correctly represents the shape, but 

 the color is different from any specimens known to me, and 

 does not accord with the text. 



122. Turricula modesta Reeve, 1. c, pi. xxxi., fig. 254. 

 Several dead specimens found on sandy flats at Samoa 



and Viti Islands. 



Our examples, though of smaller size than represented 

 by Reeve, agree in every particular with his description and
