the total length (without caudal), the length of the head three 

 times ; head about as high as long ; snout as long as the eye, 

 the diameter of which is two-sevenths of the length of the head, 

 and more than the width of the interorbital space; jaws equal 

 in length anteriorly, the maxillary extending to below the ante- 

 rior margin of the orbit. Praeorbital and angle of the prseoper- 

 culum without serratures ; opercles, throat, and isthmus entirely 

 scaly; cheek with four series of scales. The dorsal fin com- 

 mences above the end of the gill-cover, and terminates close by 

 the caudal : its spines are of moderate strength and length, and 

 can be received in a groove ; those from the fifth to the ninth 

 are the longest, not quite half as long as the head ; the last two 

 spines are equal in length ; the soft dorsal is elevated and scaly 

 at its base. The second and third anal spines are equal in length 

 and strength, and scarcely longer or stronger than those of the 

 dorsal fin ; the soft anal is similar to the corresponding part of 

 the dorsal. Caudal fin rounded, nearly one-fourth of the total 

 length; without scales, except at the base. Pectoral rather 

 narrow, extending as far backwards as the ventral, and shorter 

 than the head ; the ventral does not reach to the vent. 



Scales with the margin entire ; the upper part of the lateral 

 line terminates below the middle of the soft dorsal, above the 

 commencement of the lower part. 



The jaws, vomer, and a narrow strip of the palatine bones are 

 armed with bands of villiform teeth. The dentigerous plates on 

 the roof and on the bottom of the mouth appear to have one 

 undivided surface, no separate molar teeth being distinct : the 

 upper is oblong, slightly tapering in front, rounded behind, and 

 somewhat contracted in the middle ; the lower is elliptical, 

 and there is a smaller transverse plate behind the larger one. 



One specimen, 3^ inches long, has been presented to the 

 British Museum by Dr. F. Day. It was obtained within the 

 hill-ranges of Travancore, on the Malabar coast, where the spe- 

 cies does not appear to be very scarce.

Physical Geography for Schools and General Readers. 

 By M. F. Maury, LL.D. &c. 1864. 



This is an interesting book for young people who have to learn the 

 mutual influences of land, water, and air on the surface of the globe. 

 The rivers, lakes, and seas conform to the shape of the ground, and 

 their waters are taken up by the circulating air (or winds) to be 

 again poured down as rain ; and these processes, endlessly modified 

 in different regions, and under different chmates, both of zones and 

 heights, variously affect the aspect of nature, chiefly through the
