JIah.—OU Calabar. Coll. T. Studley, Comm. E. L. Layard, C.M.G. 



This is a most distinct and beautiful species, though in many 

 ways similar to the Xatalese A. semu/mnosa and A. grcuialata, Pfr. 

 It is thin, ovate, slightly attenuate 

 towards the apex, eight-whoiied, the ^^ 



upper whorls, and upper half of the ..^^^\ 



lowest, being minutely granular, these , ; "% 



granules being very small and regular; , .' '^v 



below the middle the last whorl is 

 smooth, and beautifully suffused with 

 bright chestnut -brown ; the ground- 

 colour of all the whorls is pale-straw, but ' \ 

 they are ornamented with longitudinal 

 dark-brown zebra-like markings. The 

 aperture is oblong, within bluish, outer 

 lip thin. 



Mr. E. L. Layard says it must be 

 common in the district whence it came, 

 since it is sold in the markets and largely 

 eaten by the natives. We hope before 

 long to obtain a full-grown specimen ; 

 and fully anticipate that when seen in 

 its finest condition this will rank as one 

 of the most striking species in the genus. 



At the request of Mr. Layard, we ^ 



name it in honour of Mr. T. iStudley, , , .. o. „ . 



.. T '' ' Achatina btadlci/i, w.^n. 



its discoverer. ^
