308 HAAS: ABIDA AND CHONDRINA. 



it. Westerlund was the first to publish a description, and thus 

 he must be accepted as the author. It happened that in its 

 description there was some such substitution as occurred in 

 the case of P. jumillensis. "Westerlund selected as type a 

 specimen having an extremely rare tooth- f ormula : 2-1-4; a 

 combination which has not been encountered again. The 

 specimens received from Hidalgo as P. kobelti, in all 179, show 

 for the most part (131 examples) the combination 2-2-3; 45 

 have 2-2-4, and only 3 have 2-2-2 teeth. The specimen drawn 

 in pi. 27, figs. 13, 14, with the combination 2-2-4 represents 

 therefore what Hidalgo required for his P. kobelti. It is from 

 the hot springs (Caldas) of Oviedo, collected by Hidalgo 

 himself. 



Pilsbry's subspecies ordunensis falls within the range of 

 variation of C. a. kobelti, as will be seen by the table given 

 above. It is represented in my material by only 2 examples. 



The area of distribution of C. a. kobelti is not yet definable 

 with certainty. All of the localities now known lie in the 

 parts of the Basque and Asturian Provinces draining into the 

 Bay of Biscay. 



Since the above was written a full discussion of the species 

 has been published by Dr. Florentino Azpeitia Moros, in Bol. 

 Soc. Iberica Ciencias Nat., XXII, 1923, pp. 105-111.
