Codltm Intertextimi Collins and Hervey. Found on several large 

 coral heads in 3 to 4 m depth at Virgin Gorda, but not 

 located within Lameshur Bay. Reported by Taylor (1960) 

 from 20 m depth. 



Codium isthomocladum Vickers. Never found within 40 m of the reef, 

 this species was occasional but conspicuous on the algal plain 

 where it often formed bushy masses up to 30 cm high in depths 

 from 14 to 31 m. It is a coiranon species with many forms, 

 occurring in the Caribbean in depths to 73 m (Taylor, 1960). 

 During feeding trails , the following fishes ate C^. isthmocladum : 

 Acanthurus bahianus , Halichoeres poeyi and Porno can thus 

 arcuatus . Randall (1967) recorded Pomo can thus paru as a 

 consumer. 



Dictyosphaeria cavernosa (Forskal) Borgesen. Common on the 



algal plain and in sea grass beds usually attached to hard 

 substrate but sometimes epiphytic in depths from 10 to 21 m. 

 Reported by Taylor (1960) from the intertidal to at least 

 55 m depth. Randall (1967) recorded Acanthurus coeruleus and 

 Alutera scripta as consumers. 



Halimeda monile (Ellis and Solander) Lamouroux. Common in grass 

 beds at Salt Pond, St. John, and along the shore of Cooper

 not seen in Lameshur Bay. Randall (1967) recorded Alutera 

 scripta and Lactophrys trigonus as consumers. 



*Halimeda scabra Howe. Found twice on the algal plain on cal- 

 careous substrate in association with Avrainvillea spp. and H. 

 incrassata in 22 m depth. Reported by Taylor (1960) from 

 shallow water to 20 m depth. Recorded here for the first time 

 from the Virgin Islands. 



Halimeda s imulans Howe. Common on the algal plain with H. 



incrassata and Avrainvillea sp. and in beds of Syringodium 

 in depths from 12 to 20 m. Reported by Taylor (1960) to 

 73 m depth. During feeding trials, the following fishes 

 ate H. s imulans : Acanthurus bahianus , A. chirurgus , Scar us
