The chestnut- banded form with the coai'se sculpture of the type 

 has been named var. fasciata by ISIr. E. R. Sykes/' 



Another banded variety may be called var, perfasciata. It is 

 similar to C. valida fasciata Sykes, but larger, the broad purpie- 

 l^rowu band more strongly contrasted with the whitish or pale buff 

 bands above and below it; aperture longer, more piriform. The 

 sculpture is perceptibly finer than in valida. The types of this 

 form are from the province Kuuchan, Okinawa Island (No. 633 

 of Mr. Hirase's collection). 



A third form of the species, var. striaiella, nov., has the color- 

 ing of var. fasciata, but darker on the last two whorls, with the 

 same rather wide aperture, dusky purplish within; but the surface 

 is far more finely striated, there being fully twice as many stride as 

 there are in valida. The size is about the same. 



Length 28, diam, 6 mm., 71 whorls remaining. 



Length 25-j, diam. 61 mm., 61 whorls remaining. 



The types ^are 79,116 Cdl. A. N. S. P., from 462 of Mr. 

 Hirase's collection, labeled " Loo Choo." 

 Clausilia Stearnsii Pilsl^ry. 



The types were taken on Okinawa by the collector sent by Mr. 

 Frederick Stearns in 1891-2. They measui*e, length 26 to 31, 

 diam. 5 mm. Specimens sent this year from Yayeyama by Mr. 

 Hirase (No. 622) measure 26-28 by 5 mm. Others sent from 

 " Loo Choo" are more slender, length 25-251, diam. 4^ mm., 

 with 12 whorls and a less distinct lunella than the tyjDes. 



C. Stearnsii is very distinct by its receding inferior lamella and 

 the development of a lunella, both being characters unlike most 

 other species of Stereopihczdusa.
