After a careful exatninatiou of fourteen specimens, all from Pensacola, 

 we have with some hesitancy reached the conclusion indicated in the 

 synonymy here given. A few of these specimens were secured with a 

 seine near Pensacola, but the majority were taken from the stomachs 

 of Eed Groupers and Red Snappers brought in by the fishing smacks. 

 A number of the latter are in very good condition but a few have been 

 more or less mutilated in the process of digestion. To the eye, four of 

 these specimens appear to have the head much larger and the cleft of 

 mouth much greater than in the others, but when the measurements 

 are taken, this apparent difference proves tangible only to the eye, as 

 no important differences in the proportion of parrs can be made. The 

 largest specimens are usually but not always those with the largest 

 mouth. There also appears to be a difference in the plumpness or stout- 

 ness, but the most plump as well as the most slender are found among 

 those of the large-mouth pattern. There is also considerable variation 

 as to the relative distance of the beginning of the dorsal from the gill- 

 opening, but the variation as shown by the small-mouthed specimens 

 is equaled by that in the others; in all, however, it is nearer the vent 

 than the gill-opening. It is probable that these differences are due to 

 a difference iu sex. In coloration and general form of body they agree 

 very well with the description of .1/. himhricus as given by Professors 

 Jordan and Gilbert. 



The name Murcena longicolUs Cuvier based on a poor figure only, with- 

 out a description, is apparently too doubtful to be adopted for this spe- 

 cies or any other. 



10. Trachunis trachurus \j. 



{Caranxomorus plumieraii us. Laccpede.) 



Specimens similar to others from the North of Europe. 



11. Pronotogrammus vivanus Jordan & Swain. 



Numerous examples, in excellent condition, taken from the stomach 

 of the Hind [Epin. drummondhayi).
