iVo/e on a Fossil FisJi from Ekoi Creek, Southern Nigeria. 

 By A. Smith Woodward, LL.D.^ F.K.S. 



An incomplete fossil fish (Brit. ]\lus. no. 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 Clupeoid or Elopine 

 species. The specimen is exposed in right side view, but the 

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

 dition, and cannot easily be interpreted. Tlie head with 

 opercular apparatus is long and narrow, probably about 

 9 cm. in length and 5 cm. in maximum depth, with a sharply 

 pointed snout; and there is no trace of external ornament 

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

 The 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, 

 ^■tout, and ncaily straight, and bears moderately large conical 

 teeth. Tlie orbit must have been very large, and the post- 

 orbital part of the check is completely covered with plates. 

 The preoperculuiu is much expanded, and has a large lower 

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