ELASMOBRANCHII. 



Genus GALEUS, Cuvier. 

 GALEUS CANIS, BONAPARIE. 



(Tope.) 

 PLATE IX., FIG. 9. 



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

 the Weybourn Crag of East Runton, 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, 

 Little Bealings, near Woodbridge, referable to this genus but 

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



Galeus canis is now living in temperate and tropical seas. 



Genus CETORHINUS, Blainville. 

 (SELACHE, Cuvier.) 



CETORHINUS MAXIMUS, LINN&US. 



(Basking Shark.) 

 PLATE IX., FIGS. 120, 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. Roy. Belg., Vol. XLI1., p. 296, 

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

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

 en passent devant le superbe male de Selache, que le docteur 

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

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

 pas ces organes a 1'etat fossile a Anvers, puisqu'on en possedait 

 au Muse'um qui provenaient du crag d'Angleterre. C'etaient 

 pre'cise'ment nos corps problematique d' Anvers qui nous avaient 

 intrigue depuis plusieurs annees." 



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

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