much more rare than the Topknot of Muller ; hut appears, 

 like it, to have an extended range. Professor Nilsson in- 

 cludes but one species in his Fishes of Scandinavia, but 

 brings together the trivial names of the hirtus of Muller and 

 the punctahis of Bloch. 



Dr. Fleming procured the true punctatus in Zetland, 

 where, according to the testimony of the fishermen, it is 

 not uncommon. Professor Henslow obtained at Weymouth 

 the specimen from which Mr. Jenyns' description and the 

 figure here inserted were taken ; and a comparison of the 

 figures and descriptions referred to under the present fish 

 with those of the Rhombus unimaculatus of M. Risso, in 

 his Histoire Naturelle, will convince the observer that they 

 are intended for the same fish. 



Bloch, if he has correctly figured his species, was, I 

 think, mistaken in supposing his fish to be the same as 

 Le Gros Plie ou Targenr of Duhamel ; as the separation 

 between the ventral and the anal fins, and the want of con- 

 nexion between the ends of both dorsal and anal fins with 

 the tail, will demonstrate on comparing the two figures : 

 but the character and disposition of the spots are something 

 like those of Muller''s fish. The figure by Dr. Fleming, 

 in his Philosophy of Zoology, wants only the greater elon- 

 gation of the first ray of the dorsal fin, perhaps a sexual dis- 

 tinction, to render it identical with the figure here given, and 

 that by M. Risso. 



I avail myself, by permission, of the very full description 

 of this fish given by Mr. Jenyns in his Manual, taken from 

 the specimen in the collection of the Philosophical Society 

 of Cambridge. 



" Length five inches and a half. Form roundish oval ; 

 the dorsal and ventral lines equally convex : greatest breadth, 

 fins excluded, just half the length : head a little less than
