220 Appendix. [No. 3, 



The inside of the shell, (b) shows two ridges proceeding from the 

 beak but not terminating in tubercles (at least not on one side ; the 

 other side was not seen). Two small teeth in the hinge terminate by 

 minute tubercles. Beak grooved by a canal or foramen. Inside of 

 ears concave. 



Avicuh-pecten Testudo, Verch. PI. VII. fig. 3 and 3a. 



Shell pyriform, umbo-marginal diameter longest. Extremely 

 gibbose. Beak pointed ; ears meeting above in a straight line. A 

 few concentric strias. Lines of growth unconspicuous, excepting one 

 near the margin. 



Avicuh-pecten Gibbosus Verch. PI. VII. fig. 4 and 4a. 



Outline sub-circular, transverse. Shell enormously gibbose, es- 

 pecially as far as the second line of growth. Shell inornate. Lines of 

 growth shallow and confused. Ears meeting in a line above the beak. 

 Shell thick. 



Remark. These Aviculo-Pectens were found in Kashmir in the 

 Wean groups only ; but in the Botta Boh they have been found here 

 and there mixed with shells of the Zeawan group, such as P. Semireti- 

 culatus, A. Subtil ita. 



Axinus, nov. spec. conf. A. Obscurus,

Found with the Aviculo-Pectens.

This shell is not rare in the Wean group near Koonmooo ; in some 

 beds it swarms in company with a small Terebratula. We have two 

 varieties, one like Mr. Salter's figure and another higher and narrower 

 Some specimens show plainly to the naked eye the punctate structure 

 of the shell.

 XXII. p. 44, PI. XI. fig. 16 ; and Spirifera Barusiensis, (David), Op. 

 Cit. p. 42, PL XI. fig. 7. 



Both these shells are found in the Wean limestone near Koonmoo, 

 and at the Bottah Boh in the flaggy limestone with Goniatites Gange- 

 ticus. I have not found them in the Zeawan group, except at the 

 Botta Boh in the mixed beds.
