EoLABROiDES gen. nov. 



An extinct genus allied to the existing Labrus, Crenilabrus, Symphodus, etc., 

 and known thus far only by the type species, which was originally described under 

 the name of Crenilabrus szajnochce Zigno. Adopting the suggestion of Dr. D. S. 

 Jordan, it may be more properly considered as the type of a distinct genus, for 

 which the new name of Eolabroides is proposed at the suggestion of the veteran 

 naturalist and supreme authority in American ichthyology, Dr. Theodore N. Gill 

 of Washington. 



Diagnosis. — An extinct genus, known only by the type species, much resembling 

 the existing Labrus, but with fewer vertebrae, and an extended dorsal fin with more 

 than twice as many soft rays as in the living genus. Scales not extending over the 

 opercular apparatus and cheeks.

A species attaining a total length of about 12 cm. to the base of the caudal fin. 

 Snout not produced and but little pointed; trunk oblong and laterally compressed. 

 Vertebrae about twenty-eight in number, of which sixteen are caudal. Dorsal fin 

 much extended, with thirteen spines and eighteen soft rays; anal fin with three 

 stout spines and eight articulated rays; caudal fin rounded, with sixteen principal 

 rays preceded by several shorter ones above and below, which are supported by 

 the epi- and hypaxial processes of the three hindermost vertebrae. Scales of 

 moderate size, finely striated, but not posteriorly serrated. Operculum and pre- 

 operculum with denticulated posterior margin. Marginal teeth conical, slightly 

 recurved; pharyngeal dentition not observed. 



Type. — Imperfect fish; present location unknown. 



Besides the type, which is small and imperfectly preserved, but one other 

 example of this species has hitherto been made known. This second specimen is 

 now the property of the Museum of Comparative Zoology at Cambridge, Mass., 

 and, like the holotype, is of small size, having a total length of 10 cm. to the base of 

 the caudal fin. In point of preservation it leaves much to be desired, and although 

 associated with the genus Symphodus by the present writer, in the opinion of Dr.
