44 I'KOCKIOIUNfiS OF THE M ALACOT.OGTCAL SOCIETY. 



C. eustoma and C. erinaceus has convinced me that Mr. Smith's view- 

 is the correct one. The statement that in C. erinaceus the umbilicus 

 is not broadl)^ funnel-shaped as in C. eustoma (Pilsbry, loc. cit ) is not 

 borne out by Pfeitfer's originail diagnosis. The shell figured in 

 Novitat. Conch., vol. ii, pi. xlvii, figs. 3, 4, and badly copied in Man. 

 Conch., vol. vi, pi. Hi, figs. 88, 89, cannot be the same as the type of 

 C. erinaceus, which, it is true, is a little larger and has the spire 

 a trifle more raised than C. eustoma, but a long series from various 

 sources, kindly furnished by Mr. Ponsonby, shows the two extremes 

 linked by intermediate forms. C. erinaceus, therefore, can only be 

 accorded varietal rank. 



The habitat "Marshall Islands" given by Pfeiiler has been called 

 in question by Dohrn and Smith, with some show of reason, and as 

 the species does not appear to have been found there by subsequent 

 collectors, it may be advisable to delete this habitat. 



In coloixr the species ranges from dull or dark ochreous yellow, 

 with white or fuscous peristome, to pale or dark russet, with violaceous 

 or fuscous peristome. 



Var. EKiNACEUs, Pfr. 



Differs from the type by its larger diameter (25-5 mm.) and the 

 slightly more raised spire. 



Chloeitis Moellendorffi, Ancey. PI. IV, Figs. A-'^c. 



CJdoritis Moellendorffi, Ancey: Proc. Linn. Soc. N. S. Wales, 1897, 

 p. 773, pi. xxxvi, fig. 7. 

 Four specimens received from Mr. W. Schliiter and labelled 

 " C. erinaceus, Tuom Island" appeared to me to agree with Ancey's 

 description of C. Moellendorffi, though not with the figure, which 

 appears imperfectly drawn, and on my sending a specimen to 

 M. Ancej^ he at once pronounced the shell to be his species. To 

 supplement Mr. Ancey's illustration, I add three views of the shell 

 and one of part of the periostracum enlarged. The shell figured 

 measures: diam. maj. 20*5, min. 18mm.; alt. 14mm. Another 

 specimen measures 18x15x13 mm., while a more depressed specimen 

 from Rubiana, New Georgia, in Mr. Ponsonby's collection, measures 

 18'5mm. in diameter, alt. 12 mm. 



Chloritis subxilis, n.sp. PL IV, Figs. 3-3c. 



Shell umbilicated, thin, fragile, subtranslucent, pale fuscous, the 

 latter part of the last whorl dark rufous, finely striated, and covered 

 with rather crowded, short, stiif , blackish bristles, arranged in quincunx. 

 Spire plane, apex slightly immersed, suture rather deep. Whorls 4J, 

 rounded, increasing rather suddenly, the last descending slowly at 

 first, then suddenly and shortly deflected in front, slightly constricted 

 behind the mouth, and compressed round the umbilicus. Aperture 

 roundly lunate, oblique, purplish inside. Peristome thin, shortly 

 expanded and reflected, violaceous purple ; margins approaching, upper 

 margin ascending shortly at first, then descending, arcuate, outer and 

 basal arcuate, columella almost straight, dilated above, and slightly
