on the inferior surface of the head. Upper jaw, as a rule, the longer. Nostrils patent, the posterior ones transverse 

 and as neav together as they are to the anterior pai/r. Barbels eight, one nasal pair, one maxillary and 

 two rnamdihula/r pairs, these last commencing in a transverse line close to the hind margin of the lower lip. Teeth 

 villiform on the jaws and palat^. Dorsal fin short, vrith one spine and six to eight rays; a very small adipose dorsal 

 which may he absorbed in the adult (^Schilbeichih/ys) .- pectoral with a serrated spi/ne : anal long, terminating at some 

 distance from a forked caudal. Ventral with from 6 to 8 rays. Air-vessel rather small, somewhat heart-shaped, with 

 a notch at its anterior edge, and closely attached to the front swrfaces of the vertebrce. An axillary pore generally 

 present. 



Geographical distribution. — Fresh waters of Sind, India, Ceylon, and Burma to the Malay Arcliipelago, 

 where Bleeker observed it appears to have a single representative.* 



Uses — These fishes are all excellent as food, but in some localities are to be avoided as they consume offal. 



SYNOPSIS OF SPECIES. 



Pseudeutropvus goongwaree, A. 54. Nasal barbels reach the dorsal, maxillary barbels the anal fin : the 

 mandibular are about as long as the head. Cleft of month to below first third of the eye. Deccan, Bengal, 

 and Burma. 



2. Pseudeutropi/us taahree, A. 43-46. / Maxillary barbels reach, middle of pectoral fin, the mandibular ones 

 shorter than the head. Deccan, Kistna, and Jumna rivers. 



3. Pseud eutropius acutirostris, A. 42-46. Snout projecting, and inferiorly covered with teeth which are 

 entirely in advance of those of the lower jaw. The maxillary barbels reach th-e anal fin, the mandibular ones 

 are as long as the head. Burma. 



4. Pseudeiitropvus murims, A. 38-43. Maxillary barbels as long as head, the others shorter. Rivers of 

 India except its more southern portion. 



5. Pseudeutropius Sykesii, A. 35-37. Maxillary barbels reach the ventral fin, the mandibular ones as long 

 as the head. Teeth on the palate in two distinct patches. 



6. Pseudeutropius atherinoides, A. 33-41. Maxillary barbels reach t^e anal fin, the mandibular are longer 

 than the head. Dark bands along the body, aiid a spot at the base of the caudal. India (except the western 

 coast) an.d Assam. 



7. Pseudeutropius garua, A. 29-36. Maxillary barbels reach the ventral fin, the mandibular pairs are 

 about as long as the head. The adipose dorsal fin is absent in adults. Throughout the large rivers of Sind, 

 India, Assam, and Burma.

Length of head 5, of caudal 5, height of body 5 in the total length. %es— with a very broad circular 

 adipose lid, situated partially on the lower surface of the head, diameter 2f in the length of head, 3/4 to 1 

 diameter from the end of snout, and 1 apart. The median longitudinal groove on the head reaches the base of 

 the occipital process, which latter is narrow, especially at its base. Width of the head rather above 1/2 its 

 length. Upper jaw the longer : width of gape of mouth equals the diameter of the eye : cleft .extends to 

 below first third of the eye. Ba/rbels— the nasal pair reach the base of the dorsal fin, the maxiUary the anal 

 fin, and the mandibular ones are about as long as the head. Teeth— m a wide pyriform band wider than those 

 in the jaws, the vomerine and palatine groups touching, but the two vomerine patches havmg a short interspace 

 between them. J'ms— dorsal spine somewhat slender, nearly as long as the head and very finely serrated 

 posteriorly. Pectoral spine slightly longer, stronger, and rather strongly denticulated internally. Ventral fin 

 not quite 1/2 as long as the head, and under the centre of the dorsal fin. Caudal forked. Free portion of the 

 tail rather higher at its base than it is long. Colours— silyeTj, darkest superiorly. , ' rrx. 



Mabitat.—niYevs of the Deccan, Bengal and Burma, attaining about a foot m length. The specimen 

 figured (life-size) was from Kurnool.

* Dr. Gunther (Geolog. Mag. Oct. 1876) determines a fossil fish from Sumatra, deficient of a head; to be a Pseudeutropius.
