18 REV. R. T. LOWE'S SUPPLEMENT TO HIS 



o 



D. 9; A. 8; P. 16; C. ^ + VIII. Rariss. 



A most elegantly-coloured little species, which I cannot refer with certainty to any 

 already described. Only two individuals have hitherto occurred. The first was little 

 more than two inches long : the second nearly twice as large. 



The Orthagoriacus of Madeira, called by the fishermen, " Peixe Porco," or " Bouto," 

 I forbear at present to designate further, not having seen a sufficient number of indi- 

 viduals to determine its characters. The caudal fin is produced into a short point in 

 the middle, not truncate, as in all the figures to which I have access of the European 

 Sun-fishes. 



Fam. Squalid^. 



Carcharias FALCiriNNis. " Faqueitc." C. corpore supra griseo-cinereo, stibabbre- 

 viato, medio crassiore s. altiore, utrinque attenuato : rostro brevi, lato, depresso, apice 

 obtuso : oculis rotundatis : pinna dorsali prima altd, triangulari, subanticu s. supra 

 medium pinnariun pectoralium positd : pinnis pectoralibus falcatis, angustis, elongatis, 

 apice obtusis : pinnd dorsali secundd analique oppositis ; ventralibusque parvis. Rariss. 



An Squalus ustus, Dum. 



It is perhaps only for want of better materials for comparison that I have been un- 

 able to refer this Shark precisely to the above-indicated or to some other described 

 species. It is about three feet long, and the female difiers in nothing from the male. 

 The teeth are precisely similar to those of the " Tintureira " (C. glaucus, Cuv.). 



The " Marraxo" proves to be, as I suspected, Lamna cornubica, Cuv., adult, or of 

 large size. 



Carcharias microps. — " Tubarao." 



The Tubarao of Madeira proves to be a genuine species of Carcharias, as defined by 

 MM. MuUer and Henle in the Magazine of Natural History for the year 1838, p. 35. 

 It is remarkable for the smallness of the eye ; and the teeth, as reported previously by 

 the fishermen, are really feeble in proportion to its bulk ; they are in only two rows, 

 and precisely similar in both jaws. The tail is very large and powerful. The individual 

 examined measured eight feet five or six inches in length. I name it only provisionally, 

 and abstain again from attempting a specific character, — deferring, in both points, to 

 the expected publication of MM. Miiller and Henle, amongst whose indicated " twenty 

 species " it will probably be found. 



Alopecias superciliosus. 



At once distinguished from the only other known species of the genus, Carcharias 

 vulpes, Cuv., by the enormous eye and its prominent brow. I have at present only 

 seen a single young example. 



Gen. Acanthidium. 

 Corpus gracile, elongatum. Spiracula magna. Pinnm dorsales duse, antice spiniferse ;
