254 Major M. ('onnolly on 



fastness into Natal or Cape Colony, the more so as it has not 

 yet been found in the intervening country. But owing to 

 the lack of detail in Krauss's figure and the marked discrep- 

 ancies between his and PfeifFer's descriptions, it is hardly 

 surprising to find that other shells, little resembling the 

 original, from widely divergent districts, have been erro- 

 neously attributed, in museum and private collections, to 

 linearis, and accepted by subsequent writers as typical of 

 Krauss's species. 'J'hus Reeve describes under this name a 

 specimen in the Cumiiig collection as a " delicate glassy shell 

 in which the suture is distinguished throughout by a fine 

 elevated ridge " (an attribute only found, in South Africa, in 

 Hypolysia jlorentice^ M. & P.), and gives the rather mixed 

 locality " Portnatal, South Africa (near the river Limpopo)." 

 Sturany also refers to examples collected by Dr. Penther in 

 Durban and Isipingo as having shiny surface and thread-like 

 suture, neither of which exists in the cotype in the Stockholm 

 Museum. 



I have not seen the shells attributed to linearis by Craven 

 from Winburg, O.R.C., or Lydenburg, Transvaal, but have 

 looked through several series from many parts of Natal, Cape 

 Colony, and Southern Transvaal, without finding anything 

 to match the Stockholm cotype ; and having regard to the 

 foregoing geographical facts, I think it may be reasonably 

 inferred that the specimens brought home by Wahlberg arc 

 possibly the only true examples of E. linearis yet known in 

 Europe, and that ail other records of its appearance have 

 been made from specimens of E. crystaUina, M. & P., H.Jlor- 

 entice, M. & P., and possibly one or two other species, yet 

 undescribed, each answering in more or less degree to Krauss's 

 description and figure, but not agreeing with his type. 



1 may here add that Mr. E. L. Layard, in his manuscript 

 notes, remarks : " linearis, Krauss, extends to Cape Town, 

 where I have procured many specimens about damp places in 

 gardens and yards, such as stones about a pump, on which 

 water was continually dripping." It is impossible to say to 

 ■what actual species Layard referred, but the note is of interest 

 as the only record of the appearance of a Stenogyra in the 

 Cape Peninsula, where nothing of the kind has been found in 

 recent years.
