354. Ancylopsetta dendritica Gilbert. 



Pl.\te XXXIII, Fig. 62. 

 //i/>Po£-/oss7tia sadatiensjs BovhENCER, 1899, p. 4. 



Infrequent; five specimens obtained. 



In this species the tubes of the lateral line are profusely branched in adults, 

 but the structure does not differ from that found in other flounders with branched 

 tubes. We are unable, therefore, to recognize the genus Ramnlaria Jordan and Ever- 

 mann (1898, p. 2G33) based on this character. The species is closely related to 

 A. quadrocellata Gill, from which it differs most strikingly in having the anterior 

 dorsal rays not produced. This also we consider of less than generic importance. 



Our specimens are smaller than the type. The depth is 1| in the length. 

 The interorbital width is about half the diameter of the upper eye. The length of 

 the maxillary is contained 2| to 2| times in the length of the head. The color is 

 blackish brown, becoming black on distal portion of vertical fins, which are narrowly 

 margined with white. The fins are similarly colored on the blind side; the head and 

 body of the blind side are also more or less washed with dark brown, especially around 

 the margins. The ocellated spots are arranged as in A. quadrocellata, but the one 

 above-the arch of the lateral line is wanting. The central light spot is yellow in life. 



In five specimens, the fin-rays are as follows:

This is the species described by Boulenger (1899, p. 4) from Rio Sabana, 

 under the name Hippoglossina sabaneiisis. 



355. Platophrys constellatus Jordan. 



Taken by the Albatross in Panama Bay, at Stations 2795, 2796, 2797, at a 

 depth of 33 fathoms (Jordan & Bollman, 1889, p. 183). 



356. Engyophrys sancti-laurentii Jordan & Bollmann. 



Panama Bay, Stations 2795 and 2805, depths 33 and 51| fathoms; recorded 

 by Gai-man (1899, p. 222). 



357. Syacium latifrons {Jordan <fc Gilbert). 



Known only from the types, which were taken at Panama. 



358. Syacium ovale {Gilniher). 



But few seen; nine specimens obtained. None of these show any tendency 

 to increased width of interorbital space.
