series behind the anus. From the caudal peduncle a rather wide band of 

 scales extends forward along the middle of the sides disappearing on the 

 trunk. Another band, narrowing anteriorly to a single series extends along 

 the mid-dorsal line to the occiput. The belly, behind the ventral fins, is finely 

 scaled. The remainder of the body Is naked except for a few small nonimbri- 

 cate scales most abundantly placed along the margin of the median scaly strip. 

 The sides of the head are partially covered with scales which are scarcely 

 imbricate. 



I here present a figure of this species, taken from one of Doctor 

 Meek's cotypes, from a stream at Refugio, Vera Cruz. This is now 

 in the United States National Museum (Cat. No. 82178, U.S.N.M.). 

 It diifers from the specimen above described by Mr. Hubbs in the 

 greater extension of the scaly area, the outer scales being imperfectly 

 formed. 



Genus HUBBESIA. 



Another aberrant Atherine is a marine species from Panama, de- 

 scribed by Jordan and Bollman,^ under the name of Menidia gilherti. 

 For this species I propose the generic name Huhhesia^ in honor of 



Fig. 2.— Hubbesia gilherti (Jordak and Bollman). 



Mr. Carl L. Hubbs, a former student, now curator of fishes in the 

 Field Museum. Huhhesia is intermediate between Menidia and 

 Membras Bonaparte, 1836 (based on Atherina onartinica Cuvier and 

 Valenciennes; apparently includes Kirtlandia). It has the scales 

 somewhat rough edged, almost as in Memhras^ but without circuli, 

 the radii conspicuously developed on the exposed field. It differs 

 from Membras {Kirtlandia) and agrees with Menidia in having the 

 first dorsal inserted before the anal, and the soft dorsal and anal free 

 from scales. The rami of the lower jaw, as in all related genera, are 

 notably elevated at base. 



Genus HEPSETIA. 



The character of the form of the rami of the lower jaw is an 

 important one in this group. It was first noticed by Mr. Henry W. 

 Fowler, who based his subgenus Atherinomorus^ on a species 

 {Atherina laticeps Poey) which differs from the type of Atherina
