SURGEON-MAJOR DAT ON SOME 



in advance of the lower. The rostral hook does not extend back- 

 wards so far as to below the orbit. Lips not fringed. Angle of mouth 

 in the middle of the length of the heacf. A patent nostril in the in- 

 terorbital space, and a tubular one before the lower eye. Teeth, palate 

 edentulous. Fins : pectorals absent ; only left ventral present, and it 

 is joined to the anal ; vertical fins confluent. Scales cycloid on both 

 sides of the body. Lateral lines, two on the left side separated by 21 

 rows of scales. Colours : left side brown, without marks. 

 Habitat. Gwadur. 20 inches in length. 



This species, having cycloid scales, may almost be separated from 

 the genus Cynoglossus, as, on the same grounds, JEsopia has been 

 from Plagusia. 



Glyptosternum madraspatanum, sp. nov. 

 D. -I | 0, P. -p V. 6, A. 2/8, C. 17. 



Length of head nearly }, of caudal f , height of body f of the total 

 length. Eyes small, in the commencement of the posterior half of 

 the length of the head. Width of head equals its length posterior to 

 the anterior nostrils. Barbels : the nasal extend two thirds of the dis- 

 tance to the orbit ; the maxillary reach the base of the pectoral spine ; 

 the external mandibular to the gill-opening, whilst the internal pair 

 are rather shorter. Occipital process very narrow, four times as wide 

 as long. Lips not fringed. Adhesive apparatus well developed. 

 Fins : dorsal spine strong, not enveloped in skin, and having a few ser- 

 rations posteriorly ; it is as long as the head from the angle of the 

 mouth ; base of adipose dorsal equals that of the rayed fin ; the pec- 

 toral almost reaches the ventral, its spine being four fifths as long as 

 the head j it is not plaited inferiorly ; the outer ventral rays are not 

 enlarged, neither are they plaited ; lower caudal lobe somewhat the 

 longer. Caudal penduncle twice as long as high. Skin smooth. 

 Colours yellowish, with dark bands; fins also yellow banded with 

 black. 



Habitat. Bowany river, at the base of the Neilgherry hills. Out of five 



specimens, the longest was 5 inches in length. 

 It differs from O. striatum more especially in the character of 

 its dorsal spine. 



Saurus indicus, sp. nov. 



B. XV. D. 13/0, P. 13, V. 9, A. 9, C. 19, L. 1. 55, L. tr. 3| | %, 

 Length of head of caudal f T , height of body T V of the total 

 length. Eyes, diameter f of the length of the head, rather above 

 1 diameter from end of snout, and 1 diameter apart. Width of snout 

 equals its length. Interorbital space somewhat concave. Internal half 

 of frontal bone corrugated, as is also the occipital, with smooth inter- 

 spaces between the striae. Upper jaw slightly the longer. Teeth, a
