﻿210 DEVONIAN FAUNA. 



Goldfuss's fig. of Pileopsis compressa seems to me to represent either this or 

 the preceding species. I have united with it the fossils now under consideration 

 because there is no sign or mention of a basal groove, but it is questionable 

 whether its spire is too much recurved to agree with either of them. 



Gapulus rostratus, Trenkner, 1 is distinguished, by its describer, from Goldfuss's 

 species by the sharpness of its back.

Description. — Shell large, depressed, trigonal, more or less wide. Spire free, 

 recurved, very small, more or less than a volution, depressed below the hori- 

 zontal plane through the top of the shell. Apex apparently much incurved, 

 minute and facing hardly if at all upwards, overhanging and generally very 

 distant from the plane of the mouth. Body-whorl more or less subcircular in 

 section, generally most convex at the back, of variable width, but generally 

 broader than high ; horizontally arched, regularly increasing, and occasionally with 

 short grooves or swellings close to the mouth, not expanded below. Mouth of 

 moderate size, nearly perpendicular to the spire. Peristome more or less sinuous. 

 Surface with irregular undulating growth-lines. 



Size. — Width 45 mm., depth 20 mm., height 27 mm. 



Localities. — From Wolborough there are two specimens in the Museum of 

 Practical Geology ; and from Lummaton there are four specimens in my 

 Collection, two in the Woodwardian, and three in the Torquay Museum, which 

 last seem to belong to the same species, and to come from the same locality. 

 There are four in the British Museum labelled " Barton." 



Remarks. — The present form seems distinguished by its minute recurved apex, 

 by its undeveloped, free, hardly elevated spire, by the distance of the apex from 

 the plane of the mouth owing to the great length of the inner side of the body- 

 whorl, and by its trigonal regularly increasing shape. Some of the specimens 

 show signs of indistinct longitudinal folds close to the mouth, and in two of them 

 these folds appear to be numerous, more definite, and more extensive. The 

 surface presents considerable inequalities or irregularities, but for the most part 

 the outer shell is lost, so that its ornamentation cannot be defined. 



From the state of the material at my command it is impossible to speak very
