Length of head from 5 to 6, of pectoral 4| to 5, of caudal 3 to 3|, height of body 5 to 6 of first dorsal 

 3 to 4, of second dorsal 5 to S^ in the total length. %e«— diameter SJ to Si in length of hea^ 1 dmmeter from 

 end of snont, and 1/6 of a diameter apart. Snont obtuse and rounded: cleft of mouth obhque its antenop 

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

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

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

 cheeks, a large opening of mucous canals opposite the posterior inferior angle of the orbit. Teethr-TnMoTm m 

 two or three rows in the upper and several in the lower jaw, the outer of w;hich is very shghtly enlarged: 

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

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

 first dorsal fin. CoZwrs— grayish-brown superiorly, becoming dull white beneath: tour or fave (sometunes 

 more) duU blotches ahnost 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 comer of the eye down the cheeks to behind the angle of the moutL 

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

 caudal, especiaUy on its central rays; the fins generaUy dark gray with a Hght outer edge. Pectoral, ventral, 

 and anal stained of a slate colour. oi ■ i. • i t. rm 



Habitat.— Seas of India to the Andaman islands, is very common up to 3^ mches m length. The 

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

Length of head 4 to 4J, of caudal 5 to 5f , height of body 5| to 6i in the total length. Eyes—mt 

 prominent, directed upwards and outwards, diameter 1/6 to 1/7 of length of head, 2 to 2^ 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 slightly the 

 longer. Cleft of mouth nearly horizontal, the maxiUa 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, becoming 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 

 triangular shape, having a median longitudinal suture. Fins — ^first dorsal spines weak, not filamentous, and 

 3/4 the height of the body : second dorsal 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 aaiterior 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 folvons, with a bluish 

 tinge along the sides, becoming dirty -white 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 through my plates of Gobies, suggests that this species of 

 Genus Awaous, is very closely allied to, if not identical with, Gohivs stamineus. VaJ. 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 maxked " Kul Oolavoo, Tam. Fresh 

 water, Gohvus B/usselUi, BusseU, pi. 63." 



Habitat. — ^Fresh and backwaters of Madras and Canara.

Length of head 3| to 4, of caudal 5 to 5|, height of body 5| to 6| in the total length. Eyes — diameter 

 1/6 of length of head, 2 diameters from end of snout, and nearly 1 diameter apart. Greatest width of head 

 equals its length behind the 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 

 longer : the maziQa 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 camne internally on either side of the symphysis ef the lower jaw.
