112. Kirtlandia gilberti (Jordan d- Bollman). 



Of this species we obtained nine specimens, which we have examined in con- 

 nection with thirteen co-types collected at Panama by the "Albatross." 



Only two of these have six dorsal spines, as described for the type; fifteen of 

 them have 5; and five of them have 4. The origin of the first dorsal in the type is 

 described as being at a point midway between the posterior margin of the heail and 

 the base of the caudal. We find that it varies from this to a point half the diameter 

 of the eye nearer to the occiput. The longest spine (probably owing to a slip of the 

 pen) is alleged to be 4| in the head. This should read 31 to 3i. The longest ray of 

 the soft dorsal exceeds the length of the snout by from one-fourth to one-half the 

 diameter of the eye. The origin of the anal varies in position from a point midway 

 between base of caudal and posterior base of pectoral (as described), to a point mid- 

 way between base of caudal and middle of upper pectoral ray; the width at base is 

 generally somewhat greater than "distance from tip of snout to base of pectorals." 

 The scales are crenate, but smooth to the touch. The dorsal and anal are scaleless. 

 The edges of the lateral band are well defined, and a nuich darker streak com- 

 poses its upper edge. It is widest under the dorsals, thence narrows on the caudal 

 peduncle and widens at base of caudal fin. Its termination is rounded.
