251a. P. unifasciatus. Id. Steindachner, Sitzb. Akad. Wiss. Wien. hi. 1, 



1867, p. 326. 

 A little known species which has not been recognised since first described.

252a. D. jerdoni. Pomacentrus jerdoni Day, P.Z.S. 1873, p. 237, ami

vi, 1881, p. 65, pi. i, 1. 



The types of P. dolii in the Macleay Museum, prove to be similar in all 



details to specimens from Queensland which I identify as D. jerdoni. They 



were doubtless stragglers from the northern waters. Length 4J inches.

 A common tropical species, which sometimes extends southward to Sydney 

 Length 6 inches. 



253b. G. leucozona. Id. Bleeker, Nat. Tijd. Ned. Ind. xix, 1859, p. 338, 



and Atlas Ichth. ix, 1877, pi. 407, 2. 

 A small species, only once taken near Sydney. 



253c. G. immaculatus. Blue Puller. Heliastes immaculatus Ogilby, 



P.L.S. N.S.W. x, 1886, p. 446; Id. Waite, Mem. Austr. Mus. iv. 1, 1899, 



p. 86, pi. 14 (PI. xxviii). 



This species is apparently better associated with the genus Glyphisodon 



than with Heliastes, though its teeth are less compressed than is usual in the 



former genus. Length 6 inches. 



(Two small specimens recorded as 67. uniocellatus Quoy & Gaimard, from 

 Sydney, by Steindachner, Sitzb. Akad. Wiss. Wien. Ivi. 1, 1867, p. 328, were 

 doubtless incorrectly identified).
