13. TricenopJioriclithys trigonocephalus^ Gill. 



14. Tricenophoriclithys harlatus^ Gthr. 



This species has been collected by Mr. Swinhoc in con- 

 siderable numbers ; and many of the specimens have the head 

 less broad than the types, the greater or lesser fulness of the 

 cheeks depending apparently on the abundance of food.

16. Eleotris Swinhoms, sp. n.

Snout and interorbital space scaleless, the remainder of the 

 head scaly. Body compressed, its depth being one fourth of 

 the total length (without caudal), the length of the head two 

 sevenths. The diameter of the eye is one fourth of the length 

 of the head, equal to that of the snout, and more than the 

 width of the interorbital space. Snout pointed, with the lower 

 jaw longest. The maxillary extends to the vertical from the 

 front margin of the eye. Greenish olive (in spirits), with more 

 or less distinct darker markings on the side of the body ; some- 

 times the markings are in the form of seven broad cross bands,

 of lighter spots.
