109. Siphostoraa auliscus Svain. 



Two specimens, 122 and 88 mm. long, were taken in ihe \l'u> firande, at 

 ]\[iraflores, near Panama. We have com|)ared them with tw(j small specimens of 

 *b'. au/i:<cii>i from Magdalona Hay, L. C, and find the only difference to he the more 

 anterior anal opening in the smaller specimen, in which it occupies the ring just 

 anterior to dorsal. In (he other specimens it is in the same ring with the front of 

 dorsal. i'lie Panama specimens are darker and more mottled. Each body ring has 

 a liroken vertical white streak, and on ahout every fifth ring is a faint dark streak. 



no. Hippocampus ingens Oirard. 



Three specimens taken, 5, 8, and 10 cm. long. Tiie smaller two, a male and a 

 female, are rough with papilliX', and have many dermal flaps. The largest one, a 

 female, is almost perfectly destitute of these, though upon close examination with 

 a lens very small, white papilhe are to he seen. 



Two si)ecimeiis from Mazatlan in the collection of the Stanford University 

 have heen examiiu'd. One is smooth, the other covered with deinial flaps. 



Family ATHERINIDiE. 

 III. Kirtlandia pachylepis (Giiniher). 



This species and K. (/i/herfi, referred to the genus Men'uUn by Jordan and 

 Evermann (1890, pp. 798 and 801), the former afterwards transferred to the genus 

 Thjrina by these authors (1898, p. 2840), belong to the genus Kirtlandia. We 

 have compared them with K. vnyi-ans, the type of the genus. Like the latter, they 

 have crenate scales, which are, however, smooth, not " very rough to the touch," as 

 described by Jordan and Evermann. Our specimens of K. vagrans and K. pachy- 

 lepis have no scales on the dorsal. The base of the anal has a row of rather long 

 scales. Both the dor.sal and anal of K. gilberti are scaleless. 



Nine specimens of K. pachijlejns were collected. They differ from Giinther's 

 description only in the slightly longer head, and in a greater range of fin-rays. 



Head and depth 5 in length of body without caudal. Eye and snout about 

 equal, ol in head. Angle of lower jaw slightly in advance of front of orbit. Inter-
