HAAS: ABIDA AND CHONDRINA. 305 



the wording of the original diagnosis seems to prescribe, but 

 that the right course is to look upon the jumillensis of Pfeiffer 

 and of Rossmaessler as one and the same race. Further, it 

 must be brought out that the dimensions ascribed to his species 

 by Pfeiffer (length 8, diam. 3.75 mm.) by no means tally; his 

 largest specimen having the tooth-combination given by him 

 as typical, and which I have designated as type, with an ac- 

 curate caliper measures only 7 mm. long and 3 mm. diameter. 

 A cotype with similar dentition, but smaller, 6.5 x 2.75 mm., 

 is figured on pi. 27, fig. 8. 



Also in the original series of the smaller jumillensis (the 

 jumillensis guiraonis), there are besides 6 examples with the 

 combination given as typical, a-1-0, also 2 with the combina- 

 tion 2-1-0. A specimen of this original series is drawn in 

 pi. 27, fig. 7. 



Pupa tarraconensis Fagot had already been described by 

 Bofill as P. jumillensis var. triplicata. Fagot, who viewed it 

 as a separate species, could not retain this name on account 

 of Pupa triplicata Studer, and had to give it a new one. This 

 form represents the combination 2-1-0, which frequently, how- 

 ever, passes into a-1-0. The snail from Sitges, Prov. Barce- 

 lona, mentioned by Rossmaessler (Iconogr. Ill, p. 110), which 

 was considered by Fagot to belong to his tarraconensis, shows 

 all of these last named combinations. A typical example from 

 Mt. Mola de Falset, Prov. Tarragona, is illustrated on pi. 27, 

 fig. 9. 



The distribution-area of C. avenacea jumillensis is to be de- 

 fined in the north only by further collecting. In the latitude 

 of Barcelona it is contiguous to that of C. a. farinesi, with 

 apparently a narrow zone of intermingling of the two. Papiol, 

 Bofill 's locality of his var. triplicata, therefore that of tarra- 

 conensis, lies close to Barcelona, and undoubted C. avenacea 

 farinesi is known to me from the same place. Sitges is the 

 northernmost locality where jumillensis alone lives. In the 

 west, Penarroyo, Prov. Teruel, is the furthest place yet known. 

 Southward we know it as far as the Cartagena- Jaen line.
