BRANNER-AGASSIZ EXPEDITION TO BRAZIL 163 



10. Tetragonopterus unilineatus Gill. 



Two small specimens were obtained among the mangroves near 

 Pernambuco. 



11. Ahlia egmontis (Jordan). 



One specimen, 150 mm. long, from the coral reef near Maceio. It 

 agrees in nearly all respects with the description of the types. The 

 dorsal fin begins behind the origin of the anal a distance equal to the 

 length of the gape of the mouth. The pectorals are broad and 

 rather short, their length slightly less than the length of the snout. 

 The length of the head equals one-fifth the distance from the snout to 

 the anus. The head and trunk are a little shorter than the tail. The 

 teeth are in a single series in each jaw, there being a few stronger 

 ones anteriorly on the head of the vomer. No teeth on the shaft of 

 vomer. The color is rather bright olive, the upper parts being densely 

 dusted with black specks. The only differences of importance be- 

 tween this specimen and the types as described consist in the smaller 

 eye and smaller mouth in the Brazilian specimen. The eye is very 

 small, about 3^ the length of the snout ; but the apparently larger eye 

 in the types may be due to imperfect state of preservation. The 

 smaller mouth is doubtless dependent upon immaturity, the types 

 being 15 inches long. 



12. Myrophis punctatus (Liitken). 



One specimen was obtained at the mouth of the Rio Goyanna. The 

 head is contained 2^ times in the trunk, 5^ in the tail. 



13. Lycodontis moringa (Cuvier). 



Mouth of the Rio Goyanna ; Pernambuco ; coral reef near Maceio. 



14. Lycodontis funebris (Ranzani). 

 Stone reef at Pernambuco. 



15. Albula vulpes (Linnaeus). 

 Pernambuco ; Maceio. 



16. Stolephorus browni (Gmelin). 

 Stone reef at Mamanguape. 



17. Lycengraulis grossidens (Cuvier). 

 Pernambuco ; one specimen. 



Head 4^ ; depth 4. D. II, 14; A. II, 25. Lateral line about 40. 



There are about 14 large teeth in a series along the middle of the 

 lower jaw. These are rather widely separated, the middle of the in- 

 terspace being occasionally occupied by a smaller tooth. Both toward 

 the angle of the jaw and toward the symphysis these larger teeth are
