NO. 23 NEW GENUS OF OPISTHOGNATHID FISHES MYERS 5 



Remarks. — I have directly compared L. lemur with Poey's two type 

 specimens of Lonchopisthus microgiiathus (U.S.N.IM. no. 4785). I 

 find that the scales in the latter are only 63 (instead of 80 or more) in 

 a longitudinal series but that there are 64 gill rakers on the first arch 

 (25 on the upper limb and 39 on the lower). There are 6 branchios- 

 tegal rays and the fin counts are as follows: Dorsal XII-17, anal 

 III-16, pectoral 17, and pelvic T-5. The head is much more compressed 

 than in L. lemur. 



Mowbray'' has described Lonchopisthus vanderbilti from " ofif the 

 coast of Cuba." From the description, this species seems to differ from 

 L. micrognathus Poey chiefly in the slightly larger scales, if it is in 

 fact a distinct species. The gill-raker count is not given. In any case. 

 Mowbray's fish is not at all close to L. lemur.
