obtained from Charts II and III of Sverdrup, et al (1946). These 

 charts were obviously redrawn from Schott (1935, pis. XX and 

 XXII). Schott also gave temperatures for May and November 

 (pis. XXI and XXIII). The temperatures that Strasburg has re- 

 corded to the nearest 0.1 degree centigrade were taken from the 

 charts, which are only general plots of whole-degree centigrade 

 isothermal lines on a map of the Pacific. The total temperature 

 range forming the basis of Strasburg's regression, 25.5-28.0° C, 

 covers only 2.5°. It is not unlikely that actual average temperatures 

 for any of Strasbiu'g's localities might differ as much as a degree from 

 those he selected. Such differences might well alter Strasburg's 

 conclusions. For this reason I am hesitant to test my counts against 

 similarly derived temperature data. 



Another point bearing on Strasburg's findings is the fact that he 

 has used method A anal fin counts. Method B counts (indeterminable 

 from his data) might have produced different results. 



Nomenclature. — The description of Salarias striatus Quoy and 

 Gaimard was based on more than one specimen (exact number not 

 mentioned) from Mauritius. There are three specimens (approxi- 

 mately 41, 44, and 58 mm SL) in the type series (MNHN A1796) in 

 the Paris Museum. All are in poor condition. I here designate the 

 largest of these three specimens lectotype. Aside from its greater 

 lengtli, the lectotype, a female, can be distinguished from the other 

 two specimens (male and female) in having the dorsal fin rays XIV, 

 16 (the 14th spine is not clearly visible) as opposed to XIII, 15 or 16 

 (13th spine not visible) for the paralectotypes, and the soft anal 

 rays 18 (the last not split to the base) as opposed to 17 (the last not 

 split to the base) or 17 (the last split to the base) in the paralectotypes. 

 The lectotype and female paralectotype have well-developed, dark 

 humeral blotches. The male paralectotype has no humeral blotch. 

 Salarias fraenatus Valenciennes was based on several specimens 

 from Bombay and although the description appears in the same work 

 as that including the original description of Salarias striatus, S. 

 fraenatus was compared only with the distantly related S. textilis. 

 The Bombay specimens differ from the types of S. striatus primarily 

 in having only a faint blotch in the humeral region, much smaller 

 than the blotch found in the types of S. striatus. S. striatus has page 

 priority over S. fraenatus. 



Salarias arenatus Bleeker was described from a single specimen, 

 62 mm, from the Cocos Islands (Indian Ocean). Chapman (1951, 

 p. 285) stated that Bleeker (1879, p. 20) synonymized S. arenatus 

 Bleeker with S. striatus. Actually, Bleeker (1875, p. 74) first gave 

 his synonymy in a paper on Madagascar fishes in which he noted the 

 •synonymy as "Salarias arenatus Blkr? = Salarias striatus Q&G CV,"
