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



Var. a. tteniata : corpore 5-6-fasciato : fasciis angustis viridibus, immaculatis. Vul- 



gatiss. 

 Var. /3. lineolata : corpore efasciato, toto lituris rufis creberrimis ad perpendiculum 



ductis sequaliter picto. Vulg. 

 Blended apparently by Valenciennes (Hist. XIII. 377.) with the blue-collared J. tur- 

 cica, Risso, under the name of J. pavo ; as formerly by me considered merely a variety 

 of J. turcica. Long-continued observations have, however, established its claim to rank 

 as a species, which is composed of two varieties, precisely corresponding with the two 

 of which the true J. turcica consists. 



JuLis MELANURA. J. oblotigus, posticc nigrcsceus : capite superne dorsoque olivaceo- 

 fuscis: lateribus perpendiculate strigatis ; strigis posterioribus nigricantibus : pinna 

 dorsalis antice altioris radiis tribus primordialibus longioribus, operculique angulo lata 

 tnincato, basique primarum pectoralium cccruleo-nigrescente notatis ; pinnd dorsali 

 analique fasciatis, basi nudis ; caudali rotundato nigricante : squamis parvis : dente 

 solitario majore ad canthum oris utrinque, antrorsum porrecto.

Julis speciosa, nob. in Syn. Mad. Fish. 186 ; baud Rissoi. 



, Cuv. et Val., Hist. 13. 375; quoad tantum exempla Canariensia, et 



forsan quidem Maderensia. 



On re- examination and a close comparison of this iish with MM. Cuvier and Valen- 

 ciennes' description of the true Mediterranean J. speciosa, of Risso, I find that it is pro- 

 perly distinct ; although a Canarian individual at least of it has been referred by Valen- 

 ciennes, as the Maderan fish was formerly by me, to Risso's species. It differs chiefly 

 in the elevation of the three first rays of the dorsal fin, the spot on which is small, not 

 large ; in the deep blackness of the caudal fin and hinder part of the tail or body ; and, 

 lastly, in being of considerably larger size (8-10 inches in length) than the true Medi- 

 terranean J. speciosa, Riss. Not having met at present with any other fishes in Madeira 

 which agree so nearly as J. melanura, with that species, I cannot help suspecting that 

 in M. Valenciennes' Maderan specimens of his J. speciosa may exist the principal pecu- 

 liarities which he has expressly noted in Mr. Webb's Canarian example, and which are 

 precisely those of Julis melanura.
