While the page proof of this bulletin was being indexed, a small 

 collection of parrotfishes was received from Dr. H. Steinitz, The 

 Hebrew University, Jerusalem. For his cooperation I am grateful. 



Whenever new material becomes available for study, new informa- 

 tion is discovered that is likely to alter conclusions. Among the 

 Steinitz collection were two species of parrotfishes, not previously 

 seen by me. One, represented by two specimens, I identify as 

 Scarus madagascarensis on the basis of color pattern and other char- 

 acters. An examination of the pharyngeal mill of one of the speci- 

 mens definitely indicated that it did not belong in the genus Scarops, 

 even though the color pattern was somewhat similar to that of 

 Scarops rubroviolaceous. 



The other species, Scarus bipallidus, is described and figured below.
