288 REConns of tiif Ar^JinAMAX musf.dm. 



Three cotypes of EJentrix hum Hi ^, De Vis, 61-98 mm. long, are, as 

 already noted by Waite, similar to tlie narrow form of C cuniinessHH. 

 L). vi/lO-11 ; A.* 11; Se. longt. 28-29; Sc. tr. 9. Depth '^S-^ in the 

 length to the hypnral joint, and subequal to the length of the head. 



As noted by Waite, there is nothing in the description of Kleufn's 

 cnvifroiis, De Vis (nee. Blyth) to distingaish it from C. cmnprensiiyt. The 

 snbstitnte name E. den'sl, Ogilby, is therefore unnecessary. 



Ciiritssiofiii loti(]i, Ogilby, is, as recognised by Waite, an elongate 

 variety of ('. ciiiiif)ressi(» ; that its slender foini is not of even snbspecific 

 value is proved by the fact that some specimens secured in the same 

 locality as the types, aie as broad as those from more northern localities. 



The uRtne ('. c(iiiiin-exsiif! viiintidiiiii, Ogilby, was proposed for slender 

 specimens fiom Killarney, Queensland, which were similar to the tyjiical 

 form in all structural details. 



Liicn. — We have examined specimens from the following localities. — 

 Clarence River, New South Wales ; cotype of Ehotrin coiuyresuKs, Kieff t r* 

 Tweed River, New South Wales ; Macleay Museum. Liverpool and 

 Mairickville, near Sydney. Jervis Bay, New South Wales; specimen 

 figured by Waite. Brisbane River, Queensland ; cotypes of E. Ii inn II in, 

 De Vis. Mary Rivei', Queensland. Port Darwin, North Australia ; 

 holotype of E. eJevntns, Macleay. 



Distn'lintioii. — Eastern waters of Anstialia fiom Cape Yoik to Jervis 

 Bay. Headwaters of the Condamine River, Queensland. Port Darwin. 



The following species are probably related to, and possibly identical 

 with (\ CDtitptt'siiiiii.

D. vi9; A. 10; P. 17; V. i/5 ; C. 15. Sc. long. 31; sc. tr. 11. 

 Depth a little more than 4 in the length without the caudal, head 3.', in 

 the same. Eye 31 in the head, longer than the snout. lireadth of the 

 snout before the eyes equal to the distance between its extremity and the 

 first third of the eye. 



Snout rather depiessed, not broad. Mouth oblique, the maxilla not 

 reaching the vertical of the anterior ocular' maigin. Head entiiely 

 s<'alv; body scales large, ctenoid and stiiated. Dorsal spines somewhat 

 filamentous. Ventrals long, inserted below the pectorals. Pectorals not 

 longer than the ventrals. 



General colour light yellow, brownish above. A small dark shoulder 

 spot, and a faint dark line along the side to the tail. Some irregular 

 oblique transverse spots on the dorsal fins, the exti'cmity of tlie second 

 black. Caudal trarrsversely s[)eckled with brown. 



LeiKjth. — Two irrches. 



This species appar-ently resembles E. re-tlniliitus, Klunzinger, from 

 the same locality, which we regai'd as svrronyrrrous with (.'. roini>ressiit/. 



Lor. — Port Darwin.
