commences below the last fourth of the dorsal fin, running along 

 the middle of the tail towards the caudal. 



The colour is now a dirty yellowish, with brown blotches. 



The single stuffed specimen, brought by Capt. King from Port 

 Famine, is 12^ inches long. 



I subjoin, for comparison, the diagnosis of 

 Chanichthys rhinoceratus.

XIII. — On certain Coleoptera from the Island of St. Vincent. 

 By T. Vernon Wollaston, M.A., F.L.S. 



In the Supplement to vol. xx. ser. 3. of the ' Annals of Natural 

 History^ 1 gave a brief notice of fifteen exponents of the Coleoptera 

 which were captured by John Gray, Esq., and the Rev. Hamlet 

 Clark, during a day's sojourn at St. Vincent (of the Cape de 

 Verdes) in December 1856, — only eleven of which, however, I 

 then attempted to determine precisely. But having lately re- 

 ceived, through the kindness of Alexander Fry, Esq., the loan of 

 various specimens which he has collected whilst touching at the 

 same island on two subsequent occasions (amounting to twenty- 

 three species, fourteen of which were not found by Messrs. Gray 

 and Clark), and having likewise had the advantage of a few 

 more (two of which were not included in either of the above- 

 mentioned batches) picked up by my nephew F. W.Hutton, Esq., 

 on the 11th of June, 1857, whilst on his voyage to Calcutta, — 

 I have got together, in all, an assortment of thirty-two species, 

 which I have just been examining somewhat carefully, with the 

 intention of supplying a few critical remarks on them in the 

 present paper. 



So little being known of the insect-population of the Cape de 

 Verdes, any contribution which may tend to elucidate even a 

 modicum of the forms that prevail there cannot but be interest- 

 ing; and when we consider the excessive barrenness of the 

 group (to which all travellers bear most abundant testimony), I 

 cannot but believe that the thirty-two species recorded below, 

 from one of the smaller islands, may give some faint idea of the 

 general character of the Coleoptera of that particular spot. As 

 we might naturally anticipate, in such a dry and cindery region.
