Dr. A. Gunther on two neio Fishes from Sarawak. 265 



amounts now to about 340, which is evidently only a fraction 

 of the number actually existing in this island. 



Two of the species were desiderata for the British Museum 

 Collection, viz. Synanceia asterohlejm (Richards.) and Apo- 

 cryptes horneensis (Blkr.) ; and the following appear to be new 

 to science : — 



Gohius Dorice. PI. XII. fig. A. 

 D. 6 1 1. A. 8. L. lat. 27. 



Head broad, depressed, rather broader than deep ; it is 

 naked, as is the nape and the lower part of the thorax ; there 

 are only a few scales on the hind part of the gill-cover. Sides 

 of the head with several series of pores. The length of the 

 head is contained thrice in the total length (without caudal), the 

 heightof the body thrice and two-thirds. Snout broad, depressed, 

 shorter than the eye, which is two-sevenths of the length of 

 the head. Cleft of the mouth wide, extending beyond the 

 front margin of the eye. Canine teeth none, Interorbital 

 space flat, broad. There are ten longitudinal series of scales 

 between the origins of the second dorsal and anal. Scales not 

 serrated. Fins low and short. Brownish black, encircled by 

 three broad yellowish bands — the first round the nape and 

 opercle, the second corresponding to the space between the 

 two dorsal fins, the third on the caudal peduncle. Caudal fin 

 yellowish, with the base deep black. 



I have named this very fine species after its discoverer. 

 Three examples, 15 lines long, are in the collection. 



EJeotris dasyrliynchus. PI. XII. fig. B. 

 D. 6 1 9. A. 8. L. lat. 29. 



Head very broad and depressed, cheeks swollen, the greatest 

 width of the head being equal to its length, without snout. The 

 gill-covers andtheupperpartof thecheekare scaly,the remainder 

 of the head naked. The prseorbital and the supraorbital ridge 

 are beset with rough prominences or spines. The length of 

 the head is contained thrice and one-third in the total length 

 (without caudal), the height of the body four times and three- 

 quarters. Snout very broad and depressed. Eyes exceed- 

 ingly small, directed upwards, separated by a broad flat space. 

 Teeth small, in a band, those of the outer series being a little 

 larger ; palate toothless. Mouth wide, the maxillary reaching 

 behind the orbit. Pr?eoperculum without spine. Scales cte- 

 noid ; there are eight longitudinal series between the origins 

 of the second dorsal and anal fins. The posterior part of the 

 second dorsal and anal are slightly elevated ; caudal rounded,
