although examples occasionally occur a couple of inches long. 

 The general, slightly curved, obtusely pointed, rapidly tapering 

 form, and peculiar horny looking texture have suggested the 

 specific name. The only described fossil it has any resemblance 

 to is the Cyrtoceras Verneuilanum of De Koninck (A. F. B. t. 48. 

 f. 6), but it is easily distinguished by that species having a broad 

 oval transverse section, while the section of the present fossil is 

 perfectly circular ; and the septa which from their obliquity ap- 

 pear oval, have their long axis directed in the opposite direction ; 

 the curvature is also less in our fossil. Some of the specimens 

 show a very slight contraction at the mouth, which renders it 

 probable that the species belongs to the subgenus Poterioceras, 

 with which all the other characters agree exactly and better than 

 with any other section of Orthoceras. 



Not very uncommon in the carboniferous limestone of Lowick, 

 Northumberland.

BIBLIOGRAPHICAL NOTICES. 



A Naturalisfs Mumbles on the Devonshire Coast. By P. H. GosSE, 

 A.L.S. &c. London: John Van Voorst, 1853. 



We shall do our readers a service at this season of the year, when so 

 many are seeking health and relaxation by the sea-shore, by directing 

 their attention to this very pleasing and useful work. Armed with 

 this and Dr. Harvey's excellent 'Sea-side Book*,' every pool will be 

 found to offer ample sources of amusement and instruction, and they 

 may bid defiance to that dire ennui which would appear to be the 

 source of the ordinary melancholy amusements of a ' watering place.' 

 We do not mean to say that people who go for relaxation to the sea- 

 side should bore themselves by taking microscopes and scalpels and 

 making scientific observations ; but without going at all deeply into the 

 subject, the search for zoophytes and moUusks will give their walks 

 something of the excitement of a hunt, and bringing them home — 

 watching their odd ways, and finding out all about them in the books 

 — will originate a vast deal of interest, and a great deal of fun and 

 humour into the bargain. At least so we have found it, and we dare 

 not venture to imagine that the ' gentle reader ' is a more dry and 

 adust personage than ourself. 



Most persons have a gustatory interest in Prawns, and indeed one 

 considers it to be part of one's mission at the sea-side to devour them 

 at breakfast and tea ; but how few of us there are who are aware that 



* Published by Van Voorst, — a book popular enough to cause a ' Reli- 

 gious ' Society to put forth a work with a title so similar, that those who 

 look no further might be readily deceived. We trust our readers will take 

 care to discourage this pious aberration.
