by Reeve. The grooves are more or less distinctly punctured, 

 and the spots as represented in Reeve's very accurate figure 

 are disposed in three transverse series on the body whorl. 

 The largest specimen shows the "hair-like" lines mentioned 

 by the above author. 



32. Mitra interlirata Reeve? 1. c, pi. x., fig. 70. 



I am somewhat doubtful in regard to the correctness of 

 the identification of the single discolored example now before 

 me, which was found on a sandy-mud flat in the Viti group. 



Mr. Reeve's description accords better with our shell 

 than his figure j but as some of his species are poorly deli- 

 neated, the latter may also be somewhat imperfect. 



I'he spiral ridges are smaller and more compressed than 

 in M. fla7nmea, and the one on the shoulder is larger and 

 more prominent than the others. The intermediate smaller 

 ridges mentioned by the above author are confined to the 

 middle of the shell. The whorls of the spire have three 

 spiral ridges, the middle one the \2iXger -jflaftimea has four of 

 nearly equal size. The color which is too much faded to be 

 of any use in a comparison, appears to have been mottled 

 similar to the latter species. The aperture seems to have 

 been white. 



Mr. Pease considered interlirata to be a variety oiflani- 

 mea. It is at least very closely related to the latter. 



33. Mitra latruncularia Reeve, 1. c, pi. xxi., fig. 166. 



We were fortunate in finding six dead but very perfect 

 specimens of this pretty species on the Kioa shore reefs, Viti 

 Islands. 



Our examples are a little smaller and more slender than 

 Reeve's figure which is not very correctly colored. The 

 whole surface is beautifully checkered with numerous small 

 chestnut-brown square spots.
