28 G. Nevill— i^'^Z of the Mollusca of [No. 1, 



1, 2 (Khasi Hills !) ; it differs widely from Mousson's Javan species, by tlie 

 acutely angled perij^hery, by its much more open umbilicus, and by the 

 broad basal band, &c. A large series of a fine variety of this species has 

 also been presented to the Museum by Mr. S. E. Peal, from the Naga Hills ; 

 this variety is of a slightly less depressed form, the umbilicus a trifle less 

 open, but its most marked characteristic is the more circular aperture, 

 which is of a deep crimson colour ; I suggest that this handsome form be 

 known as G. suhlcBvigatus, var. Pealiana, after its discoverer. C. halteatus, 

 Bens., from Pegu, is an extremely closely allied species. 



Type, from Upper Burma, axis 29, diam. 46 mil. 



Large form from Assam, axis 31, diam. 57 mil. 



Type of var. JBealicma, from the Naga Hills, axis 30, diam. 56 mil.

 Cyclophorus fulguratus, Pfr., P. Z. S. 1852, p. 52 ; Con. Indica, pi. 3, fig. 3. 

 [Var.] Cyclophorus patens, Blf., J. A. S. B., 1862 ; Con. Indica, pi. 3, fig. 5. 



This species was found in great abundance at Mimboo and Prome ; G. 

 patens, Blf., from Pegu I consider only a variety, distinguished by its round- 

 er and more thickened whorls, and especially by the less open umbilicus ; 

 G. fulguratiis is one of the commonest Burmese land-shells. 



M. Morelet states (Ser. Conch. IV, p. 283), that it is also found in Siam.

Cyclophorus zebrinus, Bens. — J. A. S. B., 1836, p. 355 (Sylhet) ; Con. Indica, pi. 2, 



fig. 2. 



Found in great abundance by Dr. Anderson at Bhamo, Hoetone, and 

 Ponsee. It aj^j^ears to be a variety of the common Khasi sjDCcies, 

 differing by its greater size and duller colouring.

Spiraculum Andersoni, Blf., P. Z. S., 1869, p. 447 (Bhamo) ; Con. Indica, pi. 86, fig. 3. 

 The type specimens were found on the First Expedition at Bhamo, 

 where the species was then very scarce ; it was obtained again on the 

 Second Expedition, living in tolerable abundance on the right bank of the 

 Irawady, Second Defile, above the Great Cliff.

Spiraculum Avanuni, Blf. J. A. S. B., 1863, p. 319 (Ava) ; Con. Indica, pi. 134, figs. 7, 8. 

 A single specimen was found on the First Expedition at Bhamo, the 

 snecies is quite distinct from S. Andersoni.
