I take the typical cccrwpictus to be the more slender, darker- 

 colored Indian form. Button's insufficient description ap- 

 pears to indicate this form, which has been figured as cceno- 

 pictus in the Conchologia Iconica and Conchologia Indica. 

 Pfeiffer figured a more obese, conic form in the Conchylien- 

 Cabinet. Somebody ought to look it up at Hutton's type 

 locality ; the exact spot should be easily found. Hutton writes : 

 ' The shell is covered over with a coating of mud. These little 

 shells I found at Beana ; they were adhering to the face. of a 

 bare and very steep rock. . . . They were scattered over the 

 bleak face of the rock in great numbers." He mentions also 

 (p. 88) that the rock faced east. 



Benson (1849) wrote: "I found the species abundant 

 under stones and rocks at Delhi, and Dr. Bacon met with it 

 in great profusion at Kurnal on mud walls and under tiles. 

 It has never occurred to me or to my correspondents on the 

 left bank of the Jumna nor of the Ganges. Dr. Bacon found 

 a specimen or two at Dinapore on the right bank of the latter 

 river, so that it has an extensive range to the south and w r est 

 of those streams." 



A. Morelet (Annali Museo Civ. de Storia Nat. di Geneva, 

 iii, 1872, p. 200) has discussed the crenopict forms described 

 from Arabia and Africa, reducing senegalensis, putilla, senna- 

 ariensis, cerealis and vermiformis to synonyms of cccnopictus; 

 even gemmula he thinks may be an insular form diminished 

 in size by the remarkable aridity of the Cape Verde Island 

 climate. 



Jickeli reduced all forms of the genus known to him to a 

 single species which he called B. fallax Say. This view is cer- 

 tainly untenable, as the American and Australian species at 

 least are quite distinct from the Asiatic and African; yet it 

 may be doubted whether the following Asiatic and African 

 forms, as far as my No. 21, are specifically distinct from 

 ccenopictus. 



P. cccnopictus appears to have been introduced in Cuba 

 and Porto Rico more than fifty years ago. Specimens from
