Pterocyclus ins ignis, Theob., var. 

 Fterocyclos insignis, Thcola., J. A. S. B., 1865 ; Con. Indica, pi, 5, figs. 6, .7. 



Three dead specimens only of this interesting form were found on the 

 First ExjDedition on the Kakhyen Hills ; the sj^ire is a trifle more depressed 

 than in typical specimens from the Shan States. 



Pteeoctcltjs Feddeni, Blf. 

 Pterocydos Fcddeni, Blf., J. A. S. B., 1865, p. 93 (Thyet Myo) ; Con. Indica, pi. 134, 



fig. 1. 



Tolerably abundant at Bhamo and above the great Cliff, Second Defile, 

 Irawady. 



Altcj^us amphoea, Bens. 



Algeceus amphora, Bens., A. & M., 1856 (Moulmein, &c.) ; Con. Indica, pi. 91, figs. 2, 3. 

 A few small specimens of this widely distributed Burmese species were 

 found at Bhamo.

(Cochin China). 

 B. Iravadica, Blf., P. Z. S. 1869 ; Con. Indica, pi. 27, fig. 10. 



A comparison of the type specimens in the Museum of B. Iravadica 

 with typical specimens of B. goniomphalus from Cochin China (received 

 from M. Morelet), prove the two species to be perfectly identical. Speci- 

 mens from Siani of B. ISiamensis, Lea (also received from M. Morelet), are 

 exceedingly closely allied, and may prove to be only a variety ; they differ, 

 however, by their smaller size, and by the last whorl being rounded and 

 not angulate, as is the case in B. goniomphalus. This species was obtained 

 abundantly by Dr. Anderson at Ava, Mandalay, and Kabyuet. 



BiTHTNIA TTJEEITA, Blf. 

 Fairbankia ? (BithijniaJ turrita, Blf., P. Z, S., 1869, p. 446 (Kyoutong). 



This most distinct and interesting species was not found on the Second 

 Expedition ; the single type in the Indian Museum, therefore, remains 

 unique. The species is, I think, a true BitJipiia, certainly not a Fairban- 

 kia. It was found at Kyoutong in Uj)per Burma. 



BiTHTNIA MOEELETIAI^A, n. sp. 



In shape resembling B. lutea, Gray, (Con. Indica, pi. 37, fig. 7) ; 

 spire peculiarly short, apex very obtuse and flattened, always eroded, but 

 not decollated ; whorls S^, the last obliquely produced ; always imj)erforate, 

 both in very young and very old shells ; margins of aperture entire, broad-
