'•ENDEAVOUR" SCIENTIFIC RESULTS- 



Genus Hvpoflectrodes, Gill. 

 HvPOPLECTKODES SEMiciNCTA, Cuvier and Valenciennes, 

 Half-banded Sea Perch. 

 Gilbertia seniicincta, Boulenger, Brit. Mus. Cat. Fish., snrt 

 ed., i., 1895, P- 307- 

 A single specimen was preserved troni six miles off Port 

 Stephens, New South Wales, 43 fathoms. 



Genus Anthias, Bloch. 

 Anthias, Boulenger, Brit. Mus. Cat. Fish., 2nd ed., i., 1895,, 

 p. 320. 



A careful examination of fourteen specimens of .4. pulchel- 

 lus, Waite, shows that the differences between this genus and 

 CcBsioperca are very slight. Comparing the definitions of the 

 two, as given by Boulenger {loc. cit., pp. 311 and 320), it 

 appears that the only reliable differences between them are 

 as follows : — 



Scales rough on the border, denticulated; tubes' of the 

 lateral line bifurcate, short. Dorsal with 19-23 rays. Anal 

 with 9-10 rays: — Ccesioperca.. 



Scales ciliated, smooth. Tubes straight or with an ascend- 

 ing tubule and extending along nearly the entire scales. 

 Dorsal with 14-18 rays. Anal with 6-8 rays: — Anthias.. 



In A. pulchellus I find the number of fin rays agrees with 

 Anthias, while the characters of the scales are distinctly those 

 of Ccesioperca. In the fourteen specimens the number of fin- 

 rays and scales is as follows: — D. X./16-17; A. iii./8; P. 

 15-16 ; 1. lat. 41-45. 



My colleague, Mr. E. F. Kallmann, very kindly pre- 

 pared microscopical mounts for me of the scales of Anthias 

 pleurotcBuia, Bleeker, A. pulchellus, Waite, Ccesioperca rasor^ 

 Rich., and C. lepidopiera, Forster. In the first-named only 

 are they smooth with ciliated edges. Those of the other 

 three have their borders roughened for varving distances

within the ciliated edges. In none do 1 find the tubes of the 

 lateral line bifurcate, as stated by Boulenger, though they 

 extend further across the scales in A. pleiirot(vnia than in the- 

 others.
