* This species is subject to some variations, or else, as Dr. Liitken suggests, we are uncertain as to 

 the number of real species that group themselves around its type. In the typical specimen of 

 ExoconiHs vokulor, 9\^ inches long-, the first ray of the pectoral is about half the fin, the second 

 ray %■ In 1 smaller specimen, 7 inches long, from the Atlantic, the first ray is | ., the longest 

 ray, or about half the second. Liitken finds the first ray scarcely % the longest, the second 

 about half the longest, and not %the third ray. In other specimens he records notable varia- 

 tions in these regards. Thisspecies may possibly prove to be the adult of E. exsiliem. 



t Dr. Vinciguerra has shown from the e.xamination of type specimens, that this species is the 

 original Exococtus rondeleii instead of the next, as was supposed by Liitken and Uleeker.
