OSTBAOIID2E. 



Genus LACTOPHBYS Swaiuson. 



5. Lactophrys trigonus (L.) Poey. 



A specimen in the State Museum at Raleigh, from Beaufort. Two 

 specimens were found on the beach at Fort Macon by Dr. Yarrow. Nu- 

 merous specimens of another species (Lactophrys quad 'n cor nis (L.)). from 

 the coast of South Carolina, are in the U. S. National Museum. This is 

 a common West Indian species, not before recorded from our coast. 



BALISTIDJE. 

 Genus ALUTEBA Cuvier. 



6. Alutera cuspicauda DeKay. — Fool-fsh. 



Bather common in Beaufort Harbor. Numerous specimens obtained. 



7. Alutera aurantiaca (Mitchill) Jor. tV Gill). — Fool-fi 



(Ceratacantliu* aurantiacus Gill, 1. c.) , 



Bather common ; with the preceding. AYe find no warrant for the genus 

 Ceratacanthus Gill, based on this species. It is certainly very closely 

 related to the preceding. 



Genus STEPHA^OLEPIS Gill. 



The genus Stephanolcpis of Gill is essentially equivalent to Monacan- 

 thus as properly restricted by Bleeker and others. In this large genus 

 there are two types, which may be called genera, each represented on 

 our coast by one species. One of these, which contains the most of 

 the species, and for which the name of StephanoJepis may be retained, 

 has the abdominal flap small, and not exceeding the ventral spine. Mon- 

 acanthus proper has the abdominal flap greatly developed, much exceed 

 ing the spine. Monacanthus setifer Bennett, of the former group, is 

 Srery common on our coast. Monacanthus occidentalis Giinther. of the 

 latter group, is probably a straggler from the West Indies. ( lanthorh in us 

 Swaiuson, occasionally used for this latter group, is apparently synony- 

 mous with Liamonacanthus Bleeker, over which name it has priority. 

 Canthorhinus, thus defined, differs from Monacanthus in having the ven- 

 tral spine immovable, and the dorsal spine without barbs. 



8. Stephanolepis setifer (Bennett) (Jill. — Common Fool-fi*h. 



One of the commonest fishes in Beaufort Harbor, swarming every- 

 where about the wharves. 



HIPPOCAMPID^E. 



Genus HIPPOCAMPUS Cuvier. 



9. Hippocampus antiquorum Leach. 



Not common. Preserved \,j fishermen as a curiosity, and sold to 

 visitors at about tweuty-five ceuts each.
