pines called R. microlepidotus (Riippell) seem to be the same, except 

 that they show several faint, blackish stripes along the back, as de- 

 scribed in R. chrysozonus (Riippell). A specimen before us from the 

 Red Sea is also R. kanagurta. 



The back in R. kanagurta is lustrous green with a row of large 

 rounded spots obscured by the silvery luster of the small but very 

 distinct scales. Traces of a row of fainter and smaller spots occur on 

 the base of the spinous dorsal; soft dorsal edged with black. 



Rastrelliger loo (Cuvier & Valenciennes) from Samoa is a different 

 species with a more pointed snout and rather slenderer body. On the 

 back are three or four rather irregular rows of very distinct black 

 spots. Rastrelliger moluccensis (Bleeker) seems to be the same as 

 R. loo. It is not certain that there are any valid species of Rastrelliger 

 except R. loo and R. kanagurta = R. brachysomus. 



Genus Auxis Cuvier. 



46. Auxis thazard Lacepede. 



Seen in the market at Colombo, but not taken. 



Genus Acanthocybium Gill. 



47. Acanthocybium sara (Lay & Bennett). 



Large examples seen in the market at Colombo, but not taken. 

 Teeth 20/20-20/20. We regard the specimens seen as probably identi- 

 cal with Acanthocybium sara from Tahiti and Hawaii. A. solandri 

 (Cuvier & Valenciennes) with double the number of teeth is a very 

 distinct species. A. petus Poey of the West Indies with the teeth 

 about 23/23 is doubtless different from either. 



Family Carangid^. 

 Genus Scomberoides Lacepede. 



48. Scomberoides tala (Cuvier & Valenciennes). 



No. 8061C, C. M. One specimen seven and one-half inches long. 



The teeth of this species distinguish it from its relatives, but they 

 have not been adequately described. 



Teeth in the mandible in two rows. The outer row consisting of 

 small, sharp, close-set, slightly irregular teeth, with a short thick 

 conical casing extending obliquely forward and outward at each side
