﻿170 DEVONIAN FAUNA. 



8. Macrochilina elevata, n. sp. PI. XVII, figs. 11, 11 a, 12, 12 a. 



Description. — Shell small, elongate, spirally conical, of five or six volutions. 

 Spire considerably more than half the height of shell, regularly increasing. 

 Suture shallow, obtuse. Whorls broad, flatly convex except at base, where they 

 slightly overhang the lower suture. Body-whorl small, curving in rapidly below. 

 Mouth widely ovate. 



Size. — Height 17 mm., width 9 mm. 



Localities. — There is a specimen in the Museum of Practical Geology from 

 Wolborough, and another in my Collection from Lummaton. 



Remarks. — The materials for describing this species are very poor and scanty, 

 the Wolborough specimen being much worn away, while the other is so obscured 

 with matrix that it is difficult to decipher its form. Nevertheless the shell differs 

 so much from the accompanying species that it certainly must be regarded as 

 distinct from them, and I am not aware of any other fossil with which it could be 

 united. 



It is distinguished by its regular conical form, its large spire, its small body- 

 whorl, and apparently by the comparative flatness of its base. 



I have given a name to this species with much hesitation on account of the 

 poorness of the available specimens. It must be regarded as only tentative, 

 although my strong impression is that further material will prove it to be distinct 

 from any described form of the genus. 



9. Macrochilina ejecta, n. sp. PL XVII, fig. 13. 



1844. Phasianella fusiformis, OolJfuss (not Sowerly). Petref. Germ., vol. iii, 



p. 113, pi. cxcviii, figs. 15 and 16. 



Description. — Shell small, rather elongate, spirally conical, of four or five 

 volutions. Suture linear, shallow, oblique. Whorls broad, almost flat, rapidly 

 increasing. Body-whorl large, more than half the height, flat and sloping in the 

 upper half, then becoming gently convex, as it turns through almost a blunt 

 angle to form the oblique base. Columella long, twisted. Mouth large, some- 

 what lozenge-shaped. Surface smooth. 



Size. — Height 12 mm., width 6 mm. 



Localities. — From Barton there is a small but perfect specimen in the Lee 

 Collection in the British Museum, and from Wolborough there are two imperfect
