Type.—Imperfect fish; Paris Museum of Natural History. 
This highly specialized and remarkable form, by Woodward regarded as 
descended from the same ancestral stock as gave rise to the Blennies, by Boulenger 
placed in association with the Sail-fishes (Histiophoride and extinet Palworhyn- 
chide), is not only typical of the genus, but has remained hitherto the only known 
representative of it and of the family Blochiide. In all, four examples are preserved 
in the Bayet Collection of the Carnegie Museum, two large-sized and_ well-pre- 
served individuals, and two smaller specimens, one of them evidently immature.
