XIX. — Neio Fishes from Angola. 

 By Dr. Albert Gunthee. 



Me. Monteieo lias brought home a small collection of fishes 

 from Angola. Some of them were collected in a lake some 

 100 miles inland of Ambriz. Besides Pellonula vorax and 

 Ophiocerphalus obscurus (with thirty rays in the anal fin) 

 and some other known forms, the following undescribed species 

 were in this collection. 



Gymnallabes apus. 



D. ca 140. A. ca 126. Body exceedingly elongate, its 

 depth being one twenty-third of the total length (without 

 caudal), the length of the head one thirteenth. Pectoral fins 

 reduced to a minute rudiment, ventrals entirely absent ; 

 vertical fins only half as high as the body. The maxillary 

 and outer mandibulary barbels are nearly equal in length, ex- 

 tending somewhat beyond the gill-opening, and rather longer
