{f) Cephalopoda. By G. C. Crick, Esq., F.G.S. 



For the subjoined notes on the Cephalopoda we are Indebted to 

 Mr. G. C. Crick, of the Natural History Museum. 



Among the specimens from the Radiolarian (Codden Hill) Beds I 

 recognize the following Goniatites : — 



1. Goniatites [Prolecanites] mixolobus, Phillips. 



2. „ „ sp . 



3. „ [Nomismoceras] spirorbis, Phillips. 



4. „ [Pericyclus], sp. 



1. Goniatites [Prolecanites] mixolobus, Phillips. 



This species is represented by at least one specimen. It shows a 

 portion of the suture-line and agrees with Phillips's type (' Geol. 

 Yorksh.' vol. ii. pi. xx. fig. 43) from the Carboniferous Limestone 

 of Bolland, Yorkshire, with which I have carefully compared it. 



I have examined the specimen belonging to the Museum of Prac- 

 tical Geology, from the Lower Culm Measures of Westleigh, North- 

 east Devon, which is marked as one of the specimens figured as 

 G. mixolobus by Prof. Phillips in his ' Palaeozoic Fossils of Cornwall, 

 Devon, etc' (pi. Ii. fig. 235; probably fig. 235/); but the fossil 

 is so imperfectly preserved that I am unable to confirm this identi- 

 fication. There are, however, in the same Museum examples from 

 Westleigh which I think are quite correctly referred to Phillips's 

 G. mixolobus. 



From Codden Hill Quarry, and Overton Quarry, near Barnstaple, 

 and from Westleigh. It also occurs in the Lower Culm of Aprath 

 and Herborn, and in the Carboniferous Limestone of Bolland, York- 

 shire, and Yise, Belgium. 



2. Goniatites [Prolecanites}, sp. 



In addition to the specimen referred to above there are several 

 forms which belong to Prolecanites, but, since only fragments of 

 their suture-lines can be made out, they are not specifically deter- 

 minable. They may be crushed examples of G. (Pr.) mixolobus, 

 but in their general character they approach closely G. (Pr.) 

 eeratitoides, von Buch, as figured by Holzapfel (Pal. Abhandl. n. s. 

 vol. i. pis. iii. & iv.) from the Lower Carboniferous of Erdbach- 

 Breitscheid, near Herborn. The Jermyn Street Museum contains a 

 similar specimen from Westleigh, North-east Devon. 



From Codden Hill Quarry and Overton Quarry, near Barnstaple, 

 and from Westleigh. 



3. Goniatites [Nomismoceras] spirorbis, Phillips. 



One specimen is clearly referable to this species, as identified by 

 Phillips from Westleigh, North-east Devon, from which locality 

 there is an example in the Museum of Practical Geology, Jermyn 

 Street. These specimens do not show the suture-line, but they are 

 most probably identical with the G. spirorbis which Phillips had
