its scaleless nape, which has a low keel on each side, scaleless breast, 

 large incisors in the sides of lower jaw, and other characters. The 

 keel on the nape is not a constant character, later examples not 

 showing it. 



On October 12, 1905, the Field Museum Expedition to Bermuda 

 obtained a very small red goby from a fragment of coral rock brought 

 up by the trawl on Challenger Bank in 30 fathoms. Owing to the 

 small size and poor condition of this specimen, it is not used as the 

 type of the species. Since that time Mr. Louis L. Mowbray has taken 

 a larger, perfect example in Hungry Bay, and this is made the type 

 which I dedicate to Mr. Mowbray in recognition of his intelligent and 

 effective work in collecting Bermudian fishes. 



This minute goby is red in life with thirteen or fourteen yellowish 

 cross-bands, three of which are in advance of the spinous dorsal. In 

 spirits the bands are brownish, and there is a rather broad orange 

 band at base of caudal. An interrupted dusky band from eye across 

 maxilla and mandible; two dusky bars downward from eye, and a 

 bifurcate dusky bar across opercle; a large dark blotch at pectoral 

 base and a smaller one on the subopercle and branchiostegal rays. 

 Eye rather large, placed high, about equal to snout, and somewhat 

 more than *4 head. Mouth oblique, with projecting lower jaw. 

 Maxilla scarcely extends behind front of eye ; lips moderately devel- 

 oped. One large canine on each side of lower jaw and a smaller one 

 behind it. Weaker canines in the upper jaw. Anterior nostril in a 

 short, dark tube; posterior nostril close to eye and in a very short 

 tube. 



Total length of type 7 /s inch ; head 3 i ; depth scarcely more than 

 Vi of total with caudal. D. vi, 10; A. 9; scales about 7-26, strongly
