B. 7. D. 4 : 60. A. 55. V. 8. P. 22 - 23. L. lat. 200. 

 L. tr. 22 : 62. 

 Head contained 4| times in total length, and greatest depth 

 4^ times. Length of snout equal to diameter of eye, and 

 about one-fifth the length of head. Distance between 

 orbits half again as broad as diameter of eye. There is 

 a series of 8 to 11 irregular teeth in upper and lower 

 jaws. Scales small. Colour uniformly dark brown. Not 

 common. 



The above form appears to be intermediate between 

 L. phyds, Schleg., and i. callarius^ Giinth. The differ- 

 ences are so marked, however, that I have thought it best 

 to raise it into specific rank for the present. I am aware 

 that there is a great variability in the allied genus 

 Pseudophycis^ and particularly in the common species 

 known here as the Rock Cod (P. barbatus)^ Giinth. ; and 

 when a larger number of individuals is examined it will 

 be seen whether the limits of variability justify the, 

 separation or not. This is the species, probably, recorded 

 in Mr. Allport's list as L. phycis.

 Common all the year round on all our coasts, and entering 

 the shallow banks of estuaries in immense numbers during 

 the winter months, when they are caught in very large 

 numbers by amateur fishermen with hook and line. The 

 young also appear in these shallows in very large numbers 

 during the months of April and May. The Rock Cod, 

 although somewhat soft, is held in great esteem as an 

 article of food. The local variety agrees with the Hmits 

 described by Prof M'Coy, is equally variable, but it 

 appears to present a local difference in the average size of 

 scale. The Derwent Rock Cod rarely has more than 100 

 rows of scales along the lateral line. In all other respects 

 it agrees with Prof. M'Coy's description already referred 

 to. Mr. Allport has P. bacchus in his MS. list ; but, as 

 P. barbatus is not referred to, I am convinced that the 

 latter was mistaken for the former. I have never seen a 

 representative of P. bacchus in Tasmanian waters.
