244 MI::M0IES OF THE QUEENSLAND MUSEUM. 



Colour. — Uniformly light -coloured after preservation, Avith the upper half 

 of the spinous dorsal dark grey ; the anal also is somewhat dusky. 



A single specimen, 99 mm. long to the end of the median caudal rays, is 

 probably referable to C. polyactis. It differs from Bleeker's figure principally in 

 being rather more slender posteriorly. 



Locality. — Near the Capricorn Group, Queensland. 



Family BOTHIDiE. 

 PLATOPHRYS PANTHERINUS Ruppell. 

 J'latophry.s jyantherinus (Ruppell) Bleeker, Atlas Ichtli. vi, 1870, p. 11, pi. ccxxxiii, fig. 3. Id. 

 Ogilby, Mem. Qld. Mus. ii, 1913, p. 90. 



Variation. — A series of seven specimens, 38-198 mm. long, which I collected 

 at Murray Island, exhibits considerable variation. Of the two largest specimens, 

 which are of almost equal length, one has the elongated pectoral rays figured by 

 Bleeker, and the orbital margins and snout are provided with several spiniform 

 rugosities. In the other the pectoral is short and the spines are wanting. 



Localities. — This species has Vjeen recorded from Darnley Island, Torres 

 Strait, by Ogilby. Australian specimens are in the Australian Museum from Murray 

 Island, Torres Strait, and from near Cape Flattery, North Queensland. Others 

 are in the collection from Lord Howe Island, Funafuti, Pleasant Island, and India. 



PLATOPHRYS POLYOPHTHALMUS Bleeker. 

 Platophrys polyophthalmiis Bleeker, Ned. Tijd. Dierk. iii, 18G6, p. 40, and Atlas Ichth. vi, 1870, 

 p. 12, pi. ccxxxiv, fig. 3. 



A specimen, 137 mm. long, differs from Bleeker's description and figure 

 only in having the ro.stro-frontal border a little more convex. The elongate pectoral 

 ray reaches nearly to the end of the dorsal, and there is a bony tubercle on the 

 anterior part of the snout and one on the anterior margin of the loAver orbit ; both 

 these characters are variable in P. j)antherinus, so evidently have no value as specific 

 characters. In all other details the specimen is as described and figured by Bleeker. 



Locality. — Between Cairns and Rockhampton, Queensland. The species has 

 not been previously recognised from Australian waters.
