These speciinens clearly belong to this Mediterranean species, which is also found 

 on the southern and eastern coasts of Spain and has been beautifully figured by Lozano 

 Rey in his monograph of the Selachians of Spain. S. fimbriata, Miiller and Henle, of 

 the Mediterranean, has been regarded as synonymous with S. oculata, but there can be 

 little doubt that it is identical with S. aculeata, Cuvier. Regan^ recorded a large specimen 

 of Squatina from Lagos as S. africana, Regan, a Natal species, but a re-examination of 

 this specimen shows that it belongs to S. oculata. The two species are very closely 

 related, but S. oculata has smaller spiracles than S. africana, with fringed anterior 

 margins, the lobes of the caudal fin more acutely pointed, and the dorsal fins narrower 

 and more acute. There are also differences in the coloration. The large example re- 

 corded by Metzelaar^ from Goree is clearly referable to 5. oculata. The following 

 represents a synopsis of the European and African species of Squatina : 



L A mid-dorsal series of enlarged denticles in the adult, forming a row of sharp spines along 



the back aculeata, Cuy.[= fimbriata, M. and Yi.] 



IL No mid-dorsal series of enlarged denticles in the adult. 



A. Dermal denticles not carinate, a large patch on lower surface between pectoral fins; 

 distance from anterior angle to posterior end of base of pectoral \ or nearly \ the 

 extreme length of the fin squatina, 'Linn. { = angelus,'Dnm.'\ 



B. Dermal denticles 3-7 carinate, none on lower surface between pectoral fins; distance 

 from anterior angle to posterior end of base of pectoral a little more than \ the extreme 

 length of the fin. 



1. Width of spiracle equal to or less than diameter of eye, its anterior margin fringed; 

 lobes of caudal fin (in adult) more or less acutely pointed oculata, Bonap. 



2. Width of spiracle greater than diameter of eye, its anterior margin not fringed; 

 lobes of caudal fin (in adult) more obtusely pointed africana, Regan
