This sIh'U has been distribute'! by Molleiidorft' mid others 

 as C'oc/ilosii/la (Ani.C(t) More/efi\ Pf., but that species is 

 (judjriiii; from the fi<Turo and descriptiorj and specimens in 

 the British Museum) but a specimen of C. {Ani.ca) Munt- 

 fortiaua, Pf., that has lost its epidermis. 



C. jiropid'ii is ch si-Iy allied to C. carJionaria, the chief 

 difference b»Mn<^ that the former is a thicker shell with a 

 much liyliter-coloured cjjidermis than the latter. C. propitia 

 is also much larger generally and broader in proportion to 

 height, and its peristome is more ex[)anded ; but these cha- 

 racters are not constant in the large series under examination. 



The great variation in the form of C propilia is shown by 

 the thiee shells selected for description. 



Aniphi'dromus cotjnotus, sp. n. (PI. IX. fig. 7.) 



Shell sinistral, moderately solid, minutely perforate, smooth, 

 ."hiniiig, whitish ground, covered on lower whorls by a bright 

 yellow perit)straeum ; whorls nearly 0, slightly convex, first 

 two dark reddish brown, remainder with dark bluish-grey, 

 narrow, spiral bands, one at tho sulure and one above the 

 middle, three on the last whorl, one about 2 mm. wide at the 

 ])eriphery, a similar one encircling the umbilieu-', and a 

 narrow one about 2 mm. below the suture, lines of growth 

 rather conspicuous ; aperture subovate, white, with the outer 

 band showing clearly through ; peristome white, moderately 

 expanded. 



^laj. diam. 17, alt. lU mm. 



In the position of the colour-bands and their showing 

 clearly through the aj)erture this species greatly resembles 

 A. heniict/cliis, llochebrune, but the latter is much narrower 

 — so narrow that one almost doubts the correctness of the 

 dimensions given, viz.: long. 30, lat. 10 mm. 



Aviphidromus niasensisy sp. n. (PI. IX. fig. 9.) 



Shell sinistral, moderately thin, finely obliquely striatal, 

 nucleus of a semitransparcnt waxy colour, rest of shell with 

 light reddish ground ornamented by rather broad oblique
