Teeth of maxillary biserial, the outer row of fourteen rather short, 

 pointed teeth; the inner row of six or seven large conical teeth the 

 pointed tips directed backwards; premaxillary with six or seven large, 

 pointed teeth set in a semicircle. Vomer with three large depressible 

 teeth anteriorly plus a biserial series on the shaft ; each row consisting 

 of about seven short, rounded teeth; lower jaw with twenty-two sharp 

 teeth on sides plus three large anterior canines on each side. 



Snout rather high and pointed, its height a third more than its 

 width; length of snout 5.5 in head; anterior nostrils in tubes near tip 

 of snout; posterior nostrils also tubular, but shorter, located directly 

 above the anterior margin of eye. Gill-openings of moderate size. 

 Eye nearer to angle of jaws than to tip of snout; its length 1.75 in 

 snout. 



No pectoral fin ; dorsal and anal well developed and meeting around 

 tip of tail; origin of dorsal on nape considerably in advance of gill- 

 openings. 



Color iti alcohol: — cherry-brown with few scattered white specks, 

 size of a pin-point, a few on anterior of body slightly larger, as large as 

 head of pin, but none so large as pupil of eye. 



Total length 281 mm.; length to anal pore 150 mm.; length of tail 

 130 mm.; length of head 40 mm. 



Type. — M. C. Z. 3960. Pearl Island, Gulf of Panama. Alexander 

 Agassiz. 



Gymnothorax pikei, sp. nov.^ 



Body cylindrical, elongate; head moderately pointed, the jaws 

 equal; tail evenly compressed from the anal pore, its length slightly 

 greater than head and trunk; depth at anal pore 2.50 in head. 



Head 7.5 in total length; 2.7 in trunk. Mouth rather large, not 

 closing completely; the under jaw being curved; length from tip of 

 snout to angle of jaws 2.1 in head. 



Teeth uniserial, the maxillary with about twelve acute teeth; pre- 

 maxillary teeth five on each side. Vomer with two large fange-like, 

 depressible teeth anteriorly, plus a single row of fourteen sharp teeth

' In 1882 Dr. Franz Steindachner studied the fishes in the Museum of Comparative 

 Zoology. During that time he labeled three jars G. pikei Steind.; G. insignis Steind.; G. 

 elegans Steind. So far as I can ascertain no descriptions were ever published; as these seem 

 to be valid new species I have described them, using the names of that eminent 

 ichthyologist.
