AN INCOMPLETE LIST OF THE MARINE FAUNA OF 

 CAMERON, LA. 



BY O. C. GLASER. 



The following is an incomplete list of the marine fauna found 

 at Cameron, La. 



Among the Polyzoa species of the following genera are abund- 

 ant: Bugula; Membranipora; Plumatella; Vesicularia. 



COELENTERATA. 



Hydroida: — Hydractinia echinata; PlumulaHa spj 



Hydromedusae : — A number of as yet undetermined Hydrome- 

 dusae occur. 



Siphonophora : — Physalia arethusa. 



Scyphomediisae : — Among the Scyphomedusae, Stomolophns 

 meleagris occurs in surprising abundance in all stages of devel- 

 opment. At times the gulf and the river are so filled with this 

 form that it is impossible to put one's hand in the water without 

 touching half a dozen. Other forms which are less abundant are 

 a species of Chrysaora, and the Cubomedusa, Chiropsalmus quad- 

 rumanus, which at times is very abundant in the gulf. 



Actiniaria: — Among the actiiiians found were Aiptasia pallida, 

 Heliactis bellis, and another species of Heliactis on the gulf weed. 



Alcyonaria: — Alcyonarians are rare. Among the forms which 

 were found were specimens of Renilla renniforniis,*- and of Lep- 

 iogorgia virgulata. 



Ctenophora: — Apparently two species of Mnemiopsis occur. 



ANNEIJDA. 



The only annelid which was found was Nereis pelagica. The 

 tubes of another as yet undetermined form are very abundant. 



MOLLUSCA. 



Lamellibranchs : — In addition to the oyster several small species 

 of clam-like forms are found. Among the better known genera 

 and species are: Area transversa; niodiola plicatula; and a small 



*Thls form was found between Cameron and Galveston.
