Spyrldia fllajnentosa G^ulf en) Hayey. Mixed with- other algae 

 and epiphytic on Ealiiiieda on the. algal plain in 15 to 21 

 TB. depth.. Reported from sRallovr water to 20 m depth.. 

 CTaylor, 1960). Randall (196.7) recorded th.e following 

 consumers : Abudef duf taurus , Acanth.urus hah.ianus , 

 Kyph-osus sectatrix, LactopKrys trigonus , Melichthys 

 niger , Pomocantkus paru , and Scarus guacamaia . 



Wrangelia argus Montagne . Occasional on the algal plain in 

 18 to 21 m depth, and once found in a grass hed attached 

 to Halimeda in 13 m depth.. Randall (1967) recorded the 

 following consumers: Eupomocentrus fuscus and Microspathodon 

 ch-rysurus . 



Wrangelia bicuspidata Borgesen. Occasional on the algal plain 

 attached to Halimeda In 18 to 23 m depth, 50 to 180 m from 

 the edge of the reef. Reported from depths to 40 m 

 CTaylor, 1960). 



Wrightiella tximanowiczi (Gatty) Schmitz. Occasional throughout 

 the algal plain in 18 to 31 depth 60 to 180 m from the 

 edge of the reef attached to Halimeda , limestone, and 

 shell, and found once in a Syringodium bed in 15 m depth 

 attached to Halimeda . Reported from 18 to 27 m (Taylor, 

 1960). During feeding trials, this species was eaten by 

 Porno can thus arcuatus and Sparisoma aurofrenatum . 



SPEEMATOPHYTA. Flowering plants. 



Halophila baillonis Ascherson. This species was encountered 



occasionally on silty, calcareous substrates in 12 to 31 m 

 depth, but was found in greatest abundance forming pure 

 stands and mixed with Syringodiina in 15 m depth bordering a 

 bare area surrounding a reef approximately 300 m south of 

 the habitat. This site was exceptional not only because 

 of the abundance of this seldom-seen species, but the plants 

 wera also flowering, apparently a very rare occurrence. 

 Halophila baillonis was found by Randall (1967) in the 

 stomach contents of the following fishes: Acanthurus 

 bahianus , A. coeruleus , Cantherhinas pullus , Canthbgaster 

 rostrata , Lactophrys triqueter , Pomocanthus paru , and 

 Sphaeroides spengleri . It is also consumed by the queen 

 conch, Strombus gigas , (Randall, 1964).
