forms, but we see no reason for doubting that ciliaris is the young of yallus, 

 as lias been supposed by Dr. Day and others. The name yallus was, how- 

 ever, originally applied by Linnaeus to Selene vomer. Our young speci- 

 mens of crinitus, moreover, agree fully with the figures of ciliaris. We 

 think it, therefore, extremely probable that all the nominal species of 

 this type are forms of Alectis ciliaris. As has been shown by Liitken 

 (Spolia Atlautica, 197), the nominal genera Scyris, Blepharis, and Gallich- 

 thys. are simply stages in the development of individuals, the charac- 

 ters assigned to these genera changing with age. (ciliaris, with long 

 lashes.)

Scyris analis, POEY, Synopsis, 369, 1868, Cuba; a large specimen without filamentous rays on 

 the anterior part of the aual; probably ail accidental variation ; the dorsal has the second

This genus has the high, compressed, angular body of Selene, the dorsal 

 and,, anal lobes not ending in filaments, and the caudal peduncle armed 

 with a few weak plates, as in Alectis. Its position is between Alectis and 

 Selene, with close affinities to both. As elsewhere stated, the separation of 

 these peculiarly formed genera from Caranx and from each other has no 

 basis in any structural character of importance. Tropical seas, (vvvic, a
