Nutc on a Fussil Fish from Ekoi Creek, Souihern Niyer'ia. 

 By A. Smith \\'()()d\vakd, LL.D., F.K.S. 



Ax incomplete fossil fish (Brit. ]\lus. uo. P. 30128) obtained 

 by Mr. J. C. Cotton from the supposed Cretaceous of Ekoi 

 Creek on the Calabar River, comprises the head and anterior 

 portion of the abdominal region of a Chipeoid or Elo|)ine 

 species. Tlic specimen is exposed in right side vicav, but the 

 bones and scales are in a much fractured and flaky con- 

 dition, and cannot easily be interpreted. The head with 

 opercular apparatus is long and narrow, probably about 

 y era. iu length and 5 cm. in maximum depth, with a sharply 

 jjointed snout ; and there is no trace of external ornament 

 on the remains of the jaws, cheek-plates, or operculum. 

 'J'he cleft of the mouth is wide, the quadrate articulation 

 being clearly seen at the hinder end of the mandible, below 

 the postorbital region of the skull. The maxilla is long, 

 btout, and nearly straight, and bears moderately large conical 

 teeth. The orbit must have been very large, and the jjost- 

 orbitul part of the cheek is completely covered with plates. 

 The preoperculmn is much expanded, and has a large lower 

 limb. Tiie pectoral tin is long and narrow, inserted well
