OSTRACIIILE. 



Genus LACTOPHEYS Swaiuson. 



5. Lactophrys trigonus (L.) Poey. 



A speciiiieu in the State Museum at Kaleigh, from Beaufort. Two 

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

 merous si)ecimens of another species {Lactophrys quadricornis (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. 



BALISTID.E. 

 Genus ALIJTEEA Cu^'ier. 



6. Alutera cuspicauda DeKay. — Fool-fish. 



1 wither common in Beaufort Harbor. Numerous specimens obtained. 



7. Alutera aurantiaca (Miteliill) Jor. & Gill). — Fool-fish. 



{CeraUicunthus aiirantiacns Gill, 1. c.) 



Eather common ; with the preceding. We find no warrant for the genus 

 (crafacantJnis Gill, ba.sed on this species. It is certainly very closely 

 related to the preceding. 



Genus STEPHANOLEPIS Gill. 



The genus ^Sfe^)hanoIepis of Gill is essentially equivalent to Monacan- 

 t It lis 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 Stephanolejjis may be retained, 

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

 «c«^^f/^^^s■ proper has the abdominal flap greatly developed, much exceed- 

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

 very common on our coast. Monacantlms occidentaUs Giinther, of the 

 latter group, is probably a straggler from the West Indies. Cauthorhbuis 

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

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

 CanihorhinvH., thus defined, difl'ers from Monacanthus in having the ven- 

 tral .spine immovable, and tlie dorsal spine without barbs. 



8. Stephaiiolepis setifer (Bennett) Gill. — Common Fool-fish. 



One of the commonest fishes in Beaufort Harlior, swarming e\'ery- 

 where about the w^harves. 



HIPPOCAMPID^. 



Genus HIPPOCAMPUS Cuvier. 



9. Hippocampu.5 antiquorum Leacb. 



Not common. Preserved Ly fishermen as a curiosity", and sold to 

 visitors at about twenty-fi\ e cents each.
