According to Koumans' synopsis of the genera of Gobiinae (1931) this species must 

 be placed either in Oxyiirichthys or in Acentrogobiiis.^ It resembles certain species of 

 Oxyiirichthys, especially in the large mouth, number of dorsal and anal rays, pointed 

 caudal, etc., but differs in the form of the dentition. It fits much better into Acentro- 

 gobitis, as defined by Koumans, and the diagnosis of that genus may be amended for 

 its reception. It appears to be related to A. schlegeli (Giinther), from which it may be 

 readily distinguished by the different dentition, the larger eye, and the greater number 

 of dorsal and anal rays.

 anterior part or middle of eye ; two large canines in lower jaw and usually two smaller 

 ones in the upper jaw. A small simple tentacle at each anterior nostril; no orbital

 1 I am greatly indebted to Dr F. P. Koumans for his kindness in examining a specimen of this species, 

 and for his opinion as to its probable systematic position. He has also examined an example of Gobius 

 angolensis.
