outer lip much thickened, crenulated o^ the inner margin 

 and slightly sinuate above; columella with five plaits. 



Length 37 mill. (Mus. Godeffroy). 



Hab. Society Islands. 



A single very perfect example was found at Tahiti. It 

 belongs to the same group as M. adusfa and ficsca. 



66. Mitra UStulata Reeve. Conch. Icon., pi. xiii., fig. 89. 



A single imperfect specimen found at Kioa, Viti Islands. 

 Though only two-thirds the size of Reeve's figure, it 

 accords in every other respect. 



67. Mitra versicolor Martyn. Reeve, 1. c, pi. i., fig. 2. 



A rare species inhabiting sheltered ground inside the 

 reefs at Tonga and Viti Islands. 



Our specimens are a little smaller than Reeve's figure 

 and the mottlings are more delicate and less conspicuous. 



Martyn's specimens were also collected at the Friendly 

 Islands,=Tonga. 



68. Mitra sp. 



We found three imperfect examples of this rather large 

 Mitra on the fringing reefs at Kioa, Viti Islands. 



It is quite distinct from any of the species figured in 

 Mr. Reeve's monograph. The specimens, together with the 

 three following species, are deposited in the Museum Godeif- 

 roy, Hamburg. 



69. Mitra sp. 



Four examples obtained at Upolo, Samoa Islands. 



70. Mitra sp. 



Three imperfect specimens were collected on the Kioa 

 fringing reefs, Viti Islands. 



71. Mitra sp. 



A single specimen obtained at Samoa.
