the south coast of Vanua Levu, Viti Islands. 



It agrees in every respect with Reeve's figure except 

 in being smaller and less robust. 



36. Mitra micans Reeve, 1. c, pi. xxxiv. , fig. 285. 



One dead but perfect example was obtained on the 

 Rarotonga reef, Cook's Islands. 



37. Mitra nevia Swainson, Reeve, 1. c, pi. vi., fig. 41. 



This very rare and graceful species was obtained at 

 Anaa, Panmotu Islands, where we found four tolerably 

 perfect dead shells, and a single much weatheied specimen 

 was picked up on the Rarotonga reef. Cook's Islands. 



The color is creamy-white, with a few smaU, irregular, 

 pale brown sutural spots. One example exhibits a few im- 

 perfect rows of minute dots of the same color in the transverse 

 grooves. 



38. Mitra nexilis Martyn. Reeve, 1. c, pi, xi., fig. 81/;. 



Excepting the Marquesas, we obtained this species in 

 more or less abundance at all the South Sea groups, but much 

 more common" at the Society, Tonga and Viti Islands than 

 elsewhere. They are invariably found on sandy bottoms 

 inside the reefs. 



Our finest examples which were obtained in the Viti and 

 Tonga groups are a little larger than Reeve's excellent figure, 

 and like the latter the spiral cord next the suture is quite 

 obsolete. Society Island specimens are smaller, darker 

 colored and the sutural cord is fully developed. 



Contrary to the views of most writers I fully believe this 

 to be a distinct species from M. filosa Born. 



39. Mitra nebulosa Swainson. Reeve, 1. c, pi. i., fig. 3. 



A rare species of which I found two dead but very 

 perfect examples on the fringing reef near Sandal-Wood Bay, 

 Viti Islands. 



Our specimens have the whorls more flattened than
