1873.] F. Stoliczka — Xand-slielh of Penang Island. 33 



Hah. — Penang et in Provincia Wellesley dicta, sub corticem Cocos nuci- 

 ferce ; testa rarissima. 



This is of exactly the same type as the Arrakanese P. filosa, described 

 at p. 333 of the Journal for last year, but it is larger, more cylindrical and has 

 one tooth more in the aperture. From P. Avanica it differs by less closely 

 wound whorls and by the interal dentition of the aperture. 



It appears to be a very rare species. I found one specimen under the 

 bark of a cocoa-nut tree on Penang, and two others on the opposite coast in 

 the Wellesley Province. 



Pupa [Pupisoma] oecella, n. sp. PL II, fig. 2. 



P. testa subglobose conoidea, apice obtusa, angustissime perforata, temii, 

 cornea ; anfractibus 3"5, valde convexis, sutura simplici junctis, transverse 

 filose striolatis ; apertura subrotundata, paululum obliqua, edentula ; margine 

 externo tenuissimo vix repandiusculo, columellari albescente, vix torto, supra 

 reflexo, umbilicum fere omnino obtegente. 



Alt, testae 1*7, diam. 1'25, alt. aperturse 0*6 m.m. 



Hah. — Penang, sub corticem Cocos nuciferce, hand frequens. 



The animal is grey with dusky pedicles, but no perceptible trace of ten- 

 tacles. The species differs from P. lignicola (1. cit.) by a shorter and broad- 

 er form, more convex whorls, and by a very slightly expanded and thin outer 

 lip. In fresh specimens some of the transverse striae of the cuticle are rather 

 stronger than others, but they very soon wear off. 



Fam. Streptaxidse. 

 This family is represented by the single species JEnnea hicoJor, occurring 

 with Stenoggra gracilis, though not very commonly. (Comp. J. A. S. B., 

 1871, vol. xl, pt. ii, p. 169). 



JFam. Veronicellidse and Vaginulidse. 



I have collected two species, which are by authors usually referred to 

 the genus Vaginulus, and with which Blainville's Veronicella is considered as 

 identical. 



The one species is the same as Vaginulit^s Birmanicus, briefly described by 

 Theobald in Journ. A. S. B., vol. xxxiii, for 1864. It is found about Calcutta, 

 extending throughout Bengal up to the base of the Sikkim hills, through 

 Arrakan, Tenasserim to Penang. A specimen obtained at Singapore does 

 not appear to differ ; E. v. Martens' V. Hasselti, (Preuss. Exp. Ost-Asien, 

 Landschnecken, 1867, p. 176, pi. 5, figs. 2 and 4) from Sumatra, Borneo, 

 &c., also appears to be the same, and it seems to me very probable that it is 

 the true Onchidium molle of Hasselt.
