52 CHONDRIN.E OP THE PYRENEAN CENTER. 



mellar immersed, palatal small, immersed ; outer margin thick- 

 ened, arcuate, columella straightened, reflected above. Length 

 7-8, diam. 2 mm. Spain. (Pupa salt us Fagot, Catal. Moll.

The shell is long, cylindric-conic, thin, slightly glossy, 

 purple-brown, distinctly but irregularly striate, composed of 

 nearly 8 whorls, rather rapidly increasing in height, weakly 

 convex, joined by a whitish, thread-like, somewhat impressed 

 suture ; the apex bluntly rounded, the last whorl contracted 

 below, with flat neck. The aperture is semiovate; on the 

 straight columella an indistinct fold stands; two of them in 

 the palate, the upper one indistinct, punctiform, the lower 

 somewhat longer ; a fourth indistinct one on the parietal wall 

 near the insertion of the peristome. The columellar reflection 

 is wide and almost half covers the large, deep umbilical crev- 

 ice. Length 3Vi> lines, width 1 line (Kuester) .

 112, pi. 15, f. 7-9. PFR., Monogr., iii, 544. 



This species is known only by the description of Charpen- 

 tier, and the figure and description of his type by Kuster. It 

 has not been found by recent collectors in Portugal, and that 

 locality must be considered dubious. It has some resemblance 

 to forms of eastern Spain. Cf. also M. avenacea apuana. 



37. CHONDRINA MASSOTIANA (Bgt.). PI. 5, fig. 5. 



Shell oval-turriculate, deeply rimate, corneous-chestnut, 

 with a very fugacious blue-white bloom when fresh, obliquely 

 striate. Spire lengthened, the summit smooth, glossy and quite 

 obtuse; 8 whorls, regularly increasing; suture deep, making 

 the whorls very convex and a little flattened towards the 

 suture ; last whorl slightly keeled around the umbilical fissure, 

 and slightly ascending in front. Aperture slightly oblique, 

 rounded-oblong, with four little teeth, as follows: one at the 

 insertion of the outer lip, the second, deeply immersed, in the 

 middle of the convexity of the penult whorl, the third in the
