88 GUDE : CLAIM TO PRIORITY OF PAPUINA WIEGMANNI. 



selected for its habitat. Probably the scarcity of moisture elsewhere 

 has been the reason why the snail at first sought such a habitat, for, 

 however dry and parched vegetation may seem the prickly pear cactus 

 has abundance of moisture, this is noticeable even in dead branches 

 where the brown sap may be seen oozing out when the decaying mass 

 has been punctured. 



E. kellettn is described by Forbes as having a " shell narrowly 

 umbilicated, depressed-globose, wrinkled, granulated, fulvous ; spire 

 subturbinated, with dirty reddish blotches and one red revolving band, 

 whorls 6, rather convex, the last with a white band at its periphery 

 and inflated on its under surface; aperture roundly lunate, light red 

 and banded within ; peristome somewhat reflected, its columellar 

 portion dilated, reflected, covering the umbilicus. Greater diameter 

 2 2, lesser 19 mm. ; height 19 mm." The shells vary so much from 

 the type that Mr. Henry Hemphill has named several varieties, such 

 as castanea, nitiihi,% multiJineata, hicolor, tricolor, alhida, etc. A shell 

 that is collected from San Diego southward on the mainland known as 

 E. stearnsiana, Gabb, is now considered only a variety of E. liellettii. 

 The animal of E. lielletti is described as of a " bluish slate-colour," 

 but the animals I have seen are nearer a drab, or cafe au lait colour. 

 I have seen none on Santa Catalina Island that might be termed 

 " slate-coloured," so evidently I have not collected the typical form, 

 so far as the animal is concerned.

 WIEGMANNI AND P. TUOMENSIS. 



By G. K. GUDE, F.Z.S. 



Papuina wiegmanni, v. Mts., from Tuom Island between Kaiser 

 Wilhelmsland and New Britain (Neu-Pommern), having been described 

 by two authors under different names, it is necessary to decide which 

 of the two names has priority. 



The circumstances of publication of the work containing the 

 earliest name and description are somewhat peculiar. The third part 

 of volume iii of ^^ Co7ic7wJoijische MiWieilungeii" in which Professor 

 von Martens first described the shell, was published in 1894, but the 

 part was directly after withdrawn from publication. I was unable to 

 obtain a copy, but Prof von Martens was kind enough to lend me his,
