the reasoning by wbieh Orycnus could be retained instead of Albacora. 
The burden of proof rests against a name having such an origin as the 
former. 
The case of Athlennes vs. Ablennes , mentioned by Dr. Gill, is not 
quite relevant. Apparently Ablennes , the name intended, should stand, 
as against Athlennes , the name printed; but surely in any case, Ath- 
lennes would not be eligible for some other group of Belonidce. 
ANALYSIS OF SPECIES OF ALBACORA. 
a. Pectoral fins long, saber-shaped, extending as far as first dorsal finlet ; their length 
about 2£ in body in adult (shorter in the young), (subgenus Germo Jordan). 
Body elliptical, elongate, and but slightly compressed. Corselet small, indis- 
tinct ; caudal keel extending forward to fifth finlet from caudal ; maxillary 
not reaching to pupil. Dorsals and anal of equal height, equal to length of 
second dorsal ; ventrals shorter. Bluish above, silvery below, sides steel-blue; 
finlets yellowish, tipped with blue. Head 3J; depth 3£. D. xiv-14-vm;

aa. Pectoral fins comparatively short, reaching to about the ninth dorsal spine ; their 
length about 6 or 7 in body in adult (shorter in the young), (subgenus Albacora )„ 
Body oblong, very robust. Corselet well developed, extending further back 
than pectorals; caudal keel extending forward to second finlet from caudal ; 
maxillary reaching to pupil. Second dorsal and anal short, 2 in the height of 
the first dorsal; ventrals longer than anal. Dark blue above; beneath soiled 
silvery with lighter spots. Head3£; depth 4. D. xiv-1, 12-vm; A. ii, 12-
