thorax do not appear at all punctured, even under the microscope ; 

 the eyes are moderate in size and in their granulation. The thorax 

 is quite twice as wide as long, the margin thick and reflexed, the 

 outer edge of the basal suture forms a ridge, so that the space 

 between this and the margin appears hollowed out. The basal 

 margin is sinuate, with a broad median lobe, and with a fine 

 marginal line. The elytra are uniformly punctured, their margin 

 somewhat expanded, with a row of larger punctures, or small foveae, 

 evanescent towards the apex. The clothing is formed of rather 

 sparse, ragged hairs, without any pubescence between them. The 

 tarsi are simple, long and thin. The humeral callus rather strongly 

 raised.

 (Plate LIV.) 



The Natural History Museum has received a large and most 

 valuable collection of Fishes, obtained at Muscat and presented by 

 Mr. Jayakar, which I have been directed by Dr. Giinther to examine. 

 This collection, containing specimens of 172 species, many of which 

 were unrepresented in the National Collection and 14 of which are 

 apparently new to science, fills a gap in our knowledge of the dis- 

 tribution of tlie fishes of the Indian Ocean. Scarcely anything is 

 known cf the fauna of the Persian Gulf and the neighbouring coasts, a 

 district intermediate between two others the fishes of which have been 

 tolerably well investigated, viz. the North-eastern coast of Africa and 

 the West coast of India. It therefore seems to me that, in addition 

 to the description of the new species, the publication of a full hst of 

 the fishes obtained will be useful. With the exception of three (the 

 names of which are preceded by an asterisk) all the species enume- 

 rated are marine.
