14 FISHES FROM BRAZIL 



33. Curimatiis elegans Steindachijer. 



Numerous specimens were taken at Lake .£fctremoz, Lake Papary and at 

 Ceara Mirim. The largest ones are almost 6 inches in length. Small ones, 

 2y2 inches long, have a black lateral band which tappers to a point and dis- 

 appears anteriorly, or it may be continued as a narrow line to the operculum. 

 The dorsal has a black spot at the middle of its base. In the large speci- 

 mens there is a rather broad diffused dark lateral^ band most evident poste- 

 riorly where it follows the lateral line, and anteriorly arching just above the 

 lateral line. The posterior part of the lateral line has a small black spot 

 above and below the pore on each scale. The dorsal spot may be pale but 

 it is usually evident. 



34, Gasterotomus latior (Spix). 



A specimen, 8 inches in length, was collected by Mr. Mann and Dr. 

 Baker in the Madeira River 400 miles from its mouth. 



The head is contained 3^ times in the length to the caudal base, and 

 the depth 24^ times, being considerably deeper than the picture published 

 by Spix (Pise. Bras. PI. 41). The front of the dorsal is midway between 

 the tip of the snout and the posterior part of the base of the adipose 

 dorsal. The pectoral is contained 1^ times in the head, and is not so long 

 as the ventral. It does not reach to the ventral, and the ventral reaches a 

 little over half way from its base to the anal. The dorsal contains 1 1 

 rays, and the anal 14. The base of the latter is equal to the combined 

 length of the snout and the eye, and the tip of the adipose dorsal is above 

 the base of the last ray. The caudal fin is broken. There are 90 series 

 of scales, all of which are roughly denticulated, but to the touch scarcely 

 feel rough. The ventral median line from the pectorals to the anal is 

 trenchant. The scales scarcely meet on the median line in front of the 

 dorsal, leaving an extremely narrow naked line. 



35. Hemiodus microlepis Kner. 



Four specimens were taken in the Rio Madeira about 400 miles above 

 its mouth by Mr. Mann and Dr. Baker. Mr. Fowler (Proc. Phil. Acad. 

 Sci. 1906, p. 319) found the "Lower lobe of caudal much longer than upper, 

 just the reverse of that indicated by Kner." In the specimens at hand two 

 of them have the upper lobe a trifle longer, one has them about equal, and 

 the other has the lower lobe a little longer. Except that these specimens are 

 considerably more slender (the depth is contained from 4^ to 4^ times 

 in the length) they agree very well with Mr. Fowler's description.
