ReTROI'INNA TASMANICA, sp. nov. 

 Tasrnauiaii Smelt. 

 (Plate xi., tig. 4.) 



Retropitina richarchonii, Johustou, Proc. Roy. Sue. Tasm., 1S82 (1883), 

 pp. 62, 128, and 1890 (1891), p. 36 (Not R. rirhanlsonil, Gill). 



D. 3/8; A. 3/16; V. 6: P. 10; C. 18. Scales mostly missing iiom 

 the liolotype, tliougli there are indications of about 74 rows between the 

 operculum and the hyiiural joint. (Other Tasmauian specimens in which 

 the scales are attached, have about 70 rows). 



Depth before the ventral fins 6'3 in the length to the hypural joint; 

 liead 5 in the same. Eye 3*2 in the head ; snout 1"3 in the eye, and ■i"3 

 in the head. Interocnlar Avidth slightly greater than the length of the 

 snout. First branched dorsal and anal rays 1"8, ventral fin 16, and 

 pectoral tin 1-4 in the head. 



Anal commencing below the anterit)r portion of the dorsal fin. Basal 

 portion of the ventral membrane covered -with small scales. JaAVS sub- 

 equal. Premaxillary teeth in a single row. Mandibular teeth in two 

 rows anteriorh', uuiserial posteriorly. Vomerine teeth in two rows, 

 palatines apparently uniserial (they are bisei'ial anteriorly in a larger 

 specimen received with the holotype). A single row of teeth on each 

 side of the tongue, with some scattered median ones between them 

 postei'iorly. 



Described and figured from a specimen 67 mm. long to the eiul of 

 the middle caudal rays, from the Huon River. 



V(in'(itlo)i. — The palatine and vomerine teeth of Tasmanian specimens 

 may be arranged in efther one or two rows. The scales are apparently 

 variable in number, but seem to be always in seventy or more rows. 

 In eleven specimens the tin-rays vary as follow: — D. 11-12; A. 17-21; 

 P. 9-11; V. 6. 



Status. — This species differs from R. semoiil in its squamation, there 

 being about seventy rows of scales instead of about fifty ; they are also 

 more developed on the nape and thoracic regions, and are distinct ou the 

 i)asal poition of the ventral membrane. The increased number of scales 

 also distinguishes /»'. hd^uuiiiira from A*, retropimui. 



Ijucidilles. — Thirteen specimens are in the Australiuii Museum fronj 

 the Huon River, and the neighbourhood of Hobart, Tasmania.
