Species 12. (Fig. a, h, Mus. Brit.) 



LiMN^A Angasi. Lim. testd suhglohosd, fused, tenu- 

 issimd, Btri(jis opacis albidis interruptis ornatd ; 

 aperturd amplissimd, antice expansd, labia externa 

 superne producto ; plied colvmellari tenui, spirali, 

 arcuatd ; spird brevissimd, acutd. 



The Angas Limn^a. Shell subglobose, brown, very 

 thin, ornamented with opaque white interrupted 

 stripes ; aperture very wide, expanded in front, 

 outer lip produced above ; columellar fold thin, 

 spiral, arched ; spire very short, acute. 



SOWERBT. 



Hah. Port Darwin, Northern Australia. 



This interesting species belongs to the Amphipepl(sa 

 group. The surface presents a positive reddish-brown 

 colour, variegated by opaque white interrupted stripes. 

 In this respect the species differs from all the other 

 known species. 



Species 13. (Mus. Sowerby.) 

 LiMN,«A ACUTA. Lim. testd subpyriformi acuminaid ; 

 subopacd ; anfractibus qwituor, quartim trihus 

 spiralihm subventricosis, distinctis, latei-alem ro- 

 tundatis, vltimo expanse, obliquo ; aperturd ovatd ; 

 labia interna angusta, plied columellari subobsoleld, 

 elevatd, vix arcuatd ; apice acuminata. 

 The acute Limn^a. Shell rather pyriform, acumi- 

 nated rather opaque ; whorls four, of which the 

 three spiral are rather ventricose, distinct, 

 laterally rounded ; the last expanded, oblique ; 

 aperture ovate; inner lip narrow, columellar fold 

 rather obsolete, raised, scarcely arched ; apex 

 acuminated. 

 Jeffhets. Briti.sh Mollusca. 

 Ilab. Great Britain, and Europe generally. 



Although having a larger and more produced spire 

 than the normal form of Liimiaa 2>ereger, it is pos- 

 sibly, as now thought by Mr. Jeffreys, only a variety of 

 that species ; yet sufficiently marked for notice.
