The chestnut- banded form with the coarse sculpture of the type 

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



Another handed variety may be called var. perfasciata. It is 

 similar to C. valida fasciata Sy^es, but larger, the broad purple- 

 browu 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 Kunchan, Okinawa Island (No. 633 

 of Mr. Hirase's collection). 



A third form of the species, var. striatella, uov., 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 striae as 

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



Length 28, diain. 6 mm., 7J whorls remaining. 



Length 25 J, diam. 6^ mm., 6J whorls remaining. 



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

 Hirase's collection, labeled " Loo Choo." 

 Ciausilia Stearnsii Pilsbry. 



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

 Frederick Stearns in 1891-2. They measure, 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 25-25 J, diam. 4J mm., 

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



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

 the development of a lunella, both being characters unlike most 

 other species of Stereoph&dusa. 



Section LUCHUPH^DUSA nov. 



Clausilium wide, truncate or notched distally, and with a thick- 

 ened lobe or finger-like process on the columellar side of the apex, 

 standing at nearly a right angle with the body of the plate. 



Shell fusiform, the right margin of the peristome usually crenate, 

 outer margin excavated above to form a sinulus; superior lamella 

 marginal, projecting, continuous with the long spiral lamella;

 specimens mentioned by Mr. Sykes.
