318 Mr. F. Smith on the Oenus Epicharis. 



throat and dorsal fin of a finner, combined with the short body 

 and large head of a true whale (Bala^nidae) . The ear-bone 

 is somewhat intermediate in form between the two groups, 

 and fully justifies my opinion that when the entire animal and 

 skeleton are known it may prove to be the type of a new 

 family of whales (Suppl. Cat. Seals & Whales, p. 41). 



I will describe the skeleton as soon as it arrives ; for there is 

 no doubt, from the proportion and size of the head and body, 

 it is a new form of whale, if it is not Neohalcena.

 three, placed in a slight curve on the vertex : antennaj genicu- 

 late ; the flagellum filiform, the first joint narrowed to its 

 base : the labial palpi four-joiuted, the two basal joints elongate, 

 the first one third longer than the second, both flattened and 

 membranaceous within ; the third and fourth minute, attached 

 near the apex of the second joint : the maxillary palpi two- 

 jointed ; the basal joint large, barrel-shaped, with its apex 

 truncate, the second joint pear-shaped and minute : mandibles

 anterior and intermediate tibite with a single spine at their 

 apex ; the posterior tibige with two spines, the inner one pecti- 

 nated : the anterior wings with one marginal cell, pointed at 

 the base and rounded at its apex, having three submarginal 

 cells, the first and second of nearly equal length, the second 

 narrowed towards the marginal celly receiving the first recm'rent 

 nervure a little beyond the middle ; the third submarginal cell 

 about two thirds of the length of the second submarginal, and 

 receiving the second recurrent nervure near its apex. 



The characters are drawn from Epicharis rustica.
