maxillaries and mandible with crowded, snout and interorbital 

 region with more or less scattered similar dots; occiput deep blue; 

 upper half of opercles with a dusky blotch ; lower half, sub-, 

 inter-, and preopercles, and the cheeks silvery: dorsal and caudal 

 jfins with a series of fine dots along each ray; a single conspicuous 

 dot at the base of each anal ray : irides silvery, clouded above 

 with deep blue. 



This beautiful species may now be definitely enrolled as a 

 regular autumn visitor to our coast; the first specimens of which 

 I know were obtained, by Mr. Whitelegge on the 31st of March, 

 1893, and a few specimens were also observed about the same 

 time during the two succeeding years. Last year they appeared 

 in large shoals in the middle of April, and they are again 

 similarly abundant at the present time. 



I take the opportunity of dedicating this species to the late 

 Prof. Edward Drinker Cope, who was the first to discover and 

 desci'ibe a herring with a dorsal serrature, in recognition of his 

 many and valuable services to science, and as a mark of personal 

 esteem for a valued and much regretted correspondent.* 



Length to 100 millimeters. 



Type in the Australian Museum, Sj'dney; register number, I. 

 3669. 



MUGIL HYPSELOSOMA, Sp.nOV. 



D. iv. i 8. A. iii 8. Sc. 40-41/U-15. 



Body short and deep, not much compressed, the ventral profile 

 much more convex than the dorsal. Length of the head 34 to 4, 

 depth of the body 3^ to 3i in the total length; width of the 

 body below the origin of the first dorsal fin If in its depth ;" 



* In the last letter which the author received from Prof. Cope, he 

 expressed his intention of reviewing the genus Dij^Iomijstus in connection 

 with the recent discovery of at least four living species. I am unaware 

 whether this intention was carried out, but it appears to me that Cope's 

 genus is clearly divisible into two.
