ELASMOBRANCHIl. 



Genus GALEIJS, Cuvier. 



GrALEUS CANIS, BONAPARIE. 



(Tope.) 

 Plate IX., Fig. 9. 



A single tooth served to indicate the presence of this species in 

 the Weybourn Crag of East Kunton, and was noticed in the 

 Survey Memoir (Vert. Forest Bed, p. 130, Plate xix., Fig. 7, 1882)., 

 Since then two other examples of these characteristic teeth have 

 been found by Mr. A. Savin in the same beds ; and the late 

 Robert Bell recognised an isolated tooth in the Pliocene deposit at 

 St. Erth, Cornwall (Plate IX., Fig. 9). 



Mr. E. C. Moor has two teeth from the Red Crag Nodule-bed, 

 Jjittle Bealings, near Woodbridge, referable to this genus but 

 probably not to this species (Plate IX., Figs. 10a, b). 



Galeus canis is now living in temperate and tropical seas. 



Genus CETORHINUS, Blainville. 

 (SELACHE, Cuvier.) 



OeTOKHINUS MAXmtJS, LINNMUS. 



{Basking Shark.) 

 Plate IX., Figs. ]2a, b. 



Some remarkable claw-like bodies, long known from the Nodule- 

 bed of the Red Crag, were recognised by Prof. Flower as agreeing 

 with the clasper-spines of the Basking Shark {Cetorhinus maximus) ; 

 but the first notice of them seems to have been published by 

 Prof. Van Beneden (Bull, Ac. Koy. Belg., Vol. XLU., p. 296, 

 1876), who says "En parcourant les galeries du British Museum 

 au raois du Mai dernier, le professeur Flower me fit remarquer, 

 en passent devaut le superbe mdle de Selache, que le docteur 

 Giinther venait de faire niettre en place, les organes appendicu- 

 laire avec leur dperons ; M. Flower me demanda si nous n'avions 

 pas ces organes h. I'^tat fossile ^ Anvers, puisqu'on en poss6dait 

 au Musdum qui provenaient du crag d'Angleterre. C'^taient 

 pr^cisdment nos corps probl6matique d' Anvers qui nous avaient 

 intrigue depuis plusieurs ann^es." 



Prof. Van Beneden in 1871 (Bull. Ac Roy. Belg., Ser. 2, 

 Vol. XXXI,, p. 504) noticed certain peculiar spinous bodies in the
