depressed, and that, looked at from underneath, very much less of 
the reflected body-whorl is visible. The largest specimen in spirit 
measures 70 mills. 
“Shell, diam. maj. 46, axis 114 , apert. lat. 404, alt. 295 mil. 
- Tolerably abundant at Momein, in Yunnan, at 5500 ft.” 
Teng-Yue-Chow is the locality given by Nevill i in his Hand-list. 
This giant of the genus was first figured by me in the P. Z. 8. 
1880, from a drawing I had made ie in Caleutta of a specimen 
in the Museum there, but at the time I subsequently described the 
genus Girasia | had no specimen of it by me toexamine. I after- 
wards received one from Mr. Geoffrey Nevill, and this I have figured 
again in this work. As will be seen by the uniting of the shell- 
lobes the shell is almost completely covered by the mantle, the 
cicatrix marking the junction of the right and left being well 
displayed. The extremity of the foot behind i is sharply keeled, and 
ends abruptly just behind the shell, which is sunk in a depression, 
as it were, anterior to the keeled foot. The mucous pore is a long 
vertical slit behind. In the odontophore the centrals are of the 
usual form in this group, but the laterals are long, curved, and 
pointed, the outer cusp being situated very much below the apex. 
In this respect it is like the labial ribbon of a species described by 
me as G. gigas var. minor of the Burrail Range, Naga Hills 
(J. A. S. B. vol. xliv. 1875, p. 10, plate iii.), a species which I have 
renamed butleri, as it is a Girasia, not an Austenia. 
The generative organs of G. magnifica are as in the type; the 
amatorial and male organs are only smaller in comparison to the 
size. Spermatophores were present in the spermatheca and were 
about 35 mm. in length, in every respect similar to those figured by 
me in the P. Z. 8. 1880, fig. 4, pl. xxvi., with some modification 
in the number and form of the cervicorn processes, as represented in 
fig. 5.

This species is thus described in my note-book :—‘‘ Animal dark 
ochre-brown, with very dark marking, particularly noticeable along 
the margin of the foot.”

Of the same form as A. gigas, but with a fine glassy lustre and 
olivaceous brown. I have now only the shell in my possession, and 
it would be very desirable to obtain more specimens from this 
locality and examine them more closely. In its shell-lobes it is
