 may be very rare, and may have been overlooked. 



The Vermilia scabra of Lamarck, is found both in Cornwall 

 and Torbay, attaclied to shells and stones. 



ON TEUEBllATULA COSTATA AND TUUBO CARNEUS. 



In reading Mr. Lowe's paper in Number V. I observed that 

 he has described two species which liad before been described in 

 works of this description, aiu! one of them figured and described 

 as British. 



Terebrahda costaia Zool. Journ. ii. 105, does not appear to 

 differ from Terebratula auritu of Fleming's Philosophy of Zoo- 

 logy, ii. p. 498, which is well figured, t. 4. f, 5, of the same work : 

 Dr. Fleming agrees with me in this idea. 



Turbo carneus, Zool. Journ. ii. 107, is certainly the same as 

 Margarita striatus of Dr. Leach, in the Appendix to Capt. Ross's 

 Voyage, as may be easily seen by his short specific character; but 

 I have verified it, by comparing the plate with the specimen of 

 the latter shell in the Museum. 



I may further inquire why is this shell placed in the genus 

 Turbo of Lamarck ; if it belongs to a)iy genus used by hinV, it is 

 certainly a Trochus, as far as the form of the mouth and structure 

 of the shell and its operculum characterizes that latter genus, and 

 therefore the removal of the other species has necessarily added 

 another synoriyma to it ; for in the works of succeeding Linneaa 

 authors it ought to be called Trochus margariius, and be placed 

 near Trochus subcarinatuSy the Ile/ix subcarinatus of Montague. 



I take this opportunity of remarking, that the article Concho.. 

 logy in the Suppl. Ency. Brit, is not by Dr. Leach, but by Dr. 

 Flemincr. J. E. G, 



ICHTHYOSAURUS. 



Several fossil remains, apparently belonging to Ichthyosauri^ 

 were found last summer in tiie blue-lias quarries of Wilmcote^ 

 three miles beyond Stratford-on-Avon ; and are now in the pos- 

 session of Mr. Greaves of Barford near Warwick. Messrs. Bur- 

 chell and Swainson who visited the spot, were informed that these
