B. V, D. 6 I T^^xT, P- ly. V. 1/5, A. ^, C. 19, L. 1. 25-28, L. tr. 6-7. 



Lengtli of bead from 5 to 6, of peotoral 4| to 5, of caudal 3 to 3§, height of body 5 to G, of firet dorsal 

 3 to 4, of second dorsal 5 to 5^ in the total length. Eijes — diameter 3j to '6\ in length of head, 1 diameter from 

 end of snout, and l/(j of a diameter apart. Snout obtuse and rounded: cleft of mouth oblique, its anterior 

 extremity commencing opposite the lower edge of the eye, the width of gape equalling length of cleft. The 

 maxilla reaches to beneath the anterior edge of the eye. Greatest width of head equals its length behind the 

 middle of the eye, whilst its height equals its length excluding the snout. A narrow row of warts across the 

 cheeks, a large opening of mucous canals opposite the posterior inferior angle of the orbit. Teeth — villiform in 

 two or three rows in the upper and several in the lower jaw, the outer of which is very slightly enlarged : 

 no canines.* Fins — spines of first dorsal weak, with filamentous terminations : last dorsal ray divided 

 at its base. Caudal lanceolate. Scales — angular, ctenoid, none on the head or in front of the base of the 

 first dorsal fin. C'o?om)-5— grayish-brown superiorly, becoming dull white beneath : four or five (sometimes 

 more) dull blotches almost forming bands pass from the back down the sides : a dark mark at the base of the 

 caudal fin. A brown band goes from the corner of the eye down the cheeks to behind the angle of the mouth. 

 Four lines of spots or bands along both dorsal fins : some obscure brownish bands sometimes present on the 

 caudal, especially on its central rays ; the fins generally dark gray with a light outer edge. Pectoral, ventral, 

 and anal stained of a slate colour. 



Habitat. — Seas of India to the Andaman islands, is very common up to 3i inches in length. The 

 specimen figured (life-size) is from Madras. Genus Acentrogohhts, Bleeker MSS.

Length of head 4 to 4^, of caudal 5 to 6|, height of body 5^ to G\ in the total length. Eyes — not 

 prominent, directed upwards and outwards, diameter 1/(3 to 1/7 of length of head, 2 to 2i diameters from end of 

 snout, and 1/2 a diameter apart. Body elongated : sides compressed. Snout elongated, cheeks inflated: head 

 4/7 as broad as long, height equals 1/2 of length : no tentacles. Jaws of equal length, or the lower shghtly the 

 longer. Cleft of mouth nearly horizontal, the maxilla reaches to nearly below front edge of the eye. Teeth — 

 in one row in the upper and in two or three rows in the centre of the lower jaw, becomuig one or two laterally, as 

 a rule no canines, but present in one specimen ; also on the inferior pharyngeal bones which are of an elongated 

 triano-iilar shape, having a median longitudinal sutui-e. Fins — first dorsal spines weak, not filamentous, and 

 3/4 the height of the body : second dors'al rays of about equal height : last dorsal ray divided to its root, it only 

 reaches 1/2 way to the base of the caudal : caudal slightly rounded. Scales — ctenoid, those anterior to the dorsal 

 fin smaller than the rest on the body : none on the cheeks and head : 30 rows between occiput and dorsal fin : 

 14 rows between the origin of the second dorsal and anal fins. Colours — generally light fulvous, with a blui-sh 

 tinge along the sides, becoming dirty-wliite beneath : some irregular bands pass from the back towards the 

 middle of the body, also some thin black lines proceed upwards on the abdomen opposite to the anal fin : 

 cheeks glossed with silver : pectoral, ventral and anal whitish-yellow : both dorsals diaphanous,_with five or six 

 rows of brown dots : caudal with eight or nine vertical rows of spots in its upper half or two-thirds._ 



Dr. Bleeker, who has been good enough to go thi-ough my plates of Gobies, suggests that this species of 

 Genus Aivaous, is very closely allied to, if not identical with, Gohias stamineus. Val. Voy. Bonite, Poissons, p. 179, 

 pi. 5, f. 5, from the Sandwich islands. 



A very good coloured figure exists amongst Sir W. Elliot's drawings marked " Kal Oolavoo, Tarn. Fresh 

 water, Oohius Russellii, Russell, pi. 63." 



Habitat.— Fresh and backwaters of Madras and Canara.

Length of head 3f to 4, of caudal 5 to 5|, height of body 5^ to GJ in the total length. Eyes — diameter 

 1/6 of leng-th of head, 2 diametere from end of snout, and nearly 1 diameter apart. Greatest width of head 

 equals its length behind tlio middle of the eyes, its height equals half its length. No warts or tentacles on the 

 head. Cleft of mouth slightly oblique, commencing opposite the lower edge of the eye, upper jaw a little the 

 lono-er : the maxilla reaches to below the front edge of the eye. Teeth — in several fixed rows in the upper jaw, 



* In one specimen there is a small canine internally on either side of tlic svmphysis of the lower jaw.
