432 NOTES AND EXHIBITS. 



Foister, from the same locality, was previously known only from 

 Lord Howe Island and New Zealand. Corythroichthys waitei 

 Jord. and Seale, from Cairns Reef, oif Cooktown, has been 

 recently described from Samoa; while Microphis pleurotcenia 

 Guuth., a Hawaiian species, is now recorded from Murray Island, 

 Torres Strait, Cairns Reef, and Masthead Island. Mr. McCulloch 

 also contributed the following Note on the identity of the Fresh- 

 water 'Perch{Percalates fluviatilis Stead): " In May, 1906, Mr. 

 Stead exhibited, before this Society, a specimen of Percalates, 

 which, in consideration of its very elongate body combined with 

 other less striking chaiacters, he proposed to distinguish under 

 the new name, F. ^fluviatiliti{These Proceedings, xxxi., 1906, 

 p. 261). The Australian Museum has recently received a tine 

 specimen of this form, which was caught at Unauderra, N.S.W. ; 

 and I have been able to compare it with others in the Museum 

 collection, identified by Mr. Ogiliy as Percalates colonorum Giinth, 

 These latter are part of the series upon which that author 

 based his opinions published in his " Edible Fishes and Crus- 

 taceans of New South Wales,"(1893, p.2). As a result of this 

 examination, I can onl}' come to the same conclusion as did Mr. 

 Ogiliy, namely, that the one is but a variation of the other; and 

 that there are intermediate forms between the two exti'emes 

 Mr. Stead also stated that he considered that none of the names 

 now taken to be synonyms of P. colonoruyn were applicable to 

 the new form. It appears to me, however, that Steindachner's 

 figure of Dules novemaculeatus{iiitzh. Ak. Wien, liii., i., 1866, 

 p. 428, PI. i., fig. 2) exactly represents the slender form; and, 

 beyond such differences as would be caused by shrinkage due to 

 different methods of preservation, (alcohol, Steindachner; and 

 formalin, Stead), it does not differ from Mr. Stead's figure 

 published in the "Edible Fishes of New South Wales,"(1908, 

 p.54, PL xxii)." 



Mr. T. H. Johnston exhibited a series of entozoa, comprising : 

 (1) Trichocephalus trichiurus Linn.,(syn. T. dispar Rud.) from 

 the csecum of the orang-outan, Siinia satyrus Geoff"r., (Sydney Zoo- 

 logical Gardens; from the East Indies); and (2) from Macacus
