less worm-like; head rather large, pointed, the snout projecting; tail 

 uniformly compressed from middle of body to tip; dorsal and anal 

 confluent around tail; length of the head and trunk about one third 

 less than length of tail; width of head almost equal to its depth; its 

 length 11 in total; 3 in trunk. Mouth of moderate size; the upper 

 jaw 3 in head; lower jaw 4.5 in head; the mouth closing fully. Teeth 

 uniserial in jaws and vomer; sharp pointed and directed backwards in 

 jaws; snout pointed 4 in head; anterior "nostril a large cone-shaped 

 tube directed downward on the upper lip just anterior to tip of lower 

 jaw, posterior nostril a slit in upper lip mid-way between anterior 

 nostril and eye; eye located on a line with angle of jaws; its length 

 2 in snout; gill-openings of moderate size lateral, being considerably 

 smaller than the distance apart. No pectoral fin. Origin of dorsal 

 about the length of head posterior to gill-openings; anal distinct. 

 Total length 100 m.; length to origin of anal 40 m.; length of head

Garmanichthys, gen. nov. 



A genus of the Myridae, characterized by absence of pectorals, the 

 high and distinct dorsal and anal with origin of dorsal near, but slightly 

 posterior to gill-openings, the vomerine teeth in a widely separated 

 series. Dorsal and anal united around tip of tail, .nostrils on upper 

 lip, the anterior in tubules the posterior an orifice opening downwards. 



Garmanichthys dentatus, sp. nov. 



Body elongate-cylindrical compressed, head moderately pointed 

 the jaws equal; tail gradually compressed from center of body; dorsal 

 and anal fins continuous around tail. 



Head 7.7 in total length; head in trunk 1.5. Total length 100 ra.; 

 length from tip of snout to origin of anal 31 ; length of tail 09, the tail 

 therefore a little more than twice the length of head and trunk; head 

 almost as wide as deep, a wide groove from occiput to tip of the rather 

 wide snout. Mouth large, the lower jaw straight; distance from tip 

 of snout to gape 2.3 in head; anterior nostril is a rather wide tube near
