MOLLUSCA OF INDIA. 237 
A precisely similar shell I note in Mr. Theobald’s collection from 
Sat Tal, near Naini Tal. 
Size: maj. diam. 18°5, min, 14°5, alt. axis 8-0 mm. 
AUSTENIA ? sERAHANENSIS, G.-A. (Plate LII. figs. 4, 4a, 46.) 
Locality. Serahan, Sutle] valley (Stoliczka). 
Shell depressedly ovate, strong, not transparent, quite smooth, with 
a thick epidermis ; colour deep ochre; spire and apex flat ; suture 
shallow ; whorls 34, rapidly increasing ; aperture narrowly ovate ; 
peristome very sinuate above; columellar margin oblique. 
Size: maj. diam. 11°5, min. 8°5, alt. axis 4:0, body-whorl 5°75 mm. 
This shell was given me by Stoliczka without a name ; it may be 
the same as the ten shells placed in H. monticola by Nevill in his 
Hand-list, p. 15. I have compared it with the young, very glassy 
shells of monticola of same size from Mussoorie, and it is very 
different. A description of the animal of this Sutlej valley form is 
much to be desired, should any conchologist again visit that part of 
the Himalayas. 
AusTENIA ? venusta, Theob. (Plate LIX. figs. 5, 5a.) 
Locality. Arakan (Theob.). 
Helicarion venustum, Theob. Journ. A. 8. B. 1870, p. 400; 1877, 
p. 24 (is another species). 
Vitrina venusta, Hanley, Conch. Ind. p. 61, pl. cli. fig. 5, from 
Arakan Hills, between Tongoop and Prome *. 
Helicarion (sec. B) venustus, Theob. Supp. Cat. p. 23. 
Vitrina (sec. 2. Phenacclimax) venusta, Pfr. Cless. Nomen. Helic. 
Vivent. p. 27 (1881). 
Helicarion (Austenia) venustus, Nevill, Hand-list, p. 16. no. 32, 
from Arakan, Yunnan, and Kakhyen Hills: as No. 33 (ZH. solida, 
G.-A.) is referred to this shell with a query, I doubt if the identifica- 
tion of these species is correct; typical venustus is quite different 
from cacharica=solida, which is the species Nevill had before him, 
Original description :—‘ Vitrina? venusta. Testa ovato-auri- 
forme, supra vix convexa, diaphana, tenuissima, polita, subrugose 
striata, lete flavescente brunnea ; anfractibus 13 celerissime crescenti- 
bus ; apertura latissima. 
* Diam. major 0-30, diam. minor 0°17, alt. 0°10 inch. 
‘“* Habitat prope ‘ Chuegale Sakan, montibus Arakan’ dictis inter 
Tonghup et Prome.” 
Mr. Theobald compares it with, and considers it closely allied to, 
the Nilghiri V. auriformis ; but a comparison of the shells alone will 
show they are quite different, while now we know the slug-like 
forms of Southern India are a widely divergent group. 
Under this species Nevill writes as follows, in his paper on the 
Mollusca of Upper Burmah and Yunnan :— 
‘** Dr. Anderson brought back from Ponsee, in Yunnan, numerous
