154¡ Report on some Fishes received from Sitang River. [No. 2, 



in the second volume of the Calcutta Journal of Natural History, 



pp. 584-8. 



The species first described by liim is his Gl. reticulattjs, frora 

 Afghánistán. It is stated to be " without spines ; the first ray of 

 the pectoral and ventral fins soft and pinnate, giving oíf soft pointed 

 cartilaginous rays along the anterior margin, which are enveloped in 

 the membrane of the fin. The under surface of the liead and of the 

 anterior portion of the oody fonns a fíat corrugated surface" Gill- 



covers ? Cirri ? This form will remain as typical Glyp- 



tosternon. 



A second type (Psettdecheneis, nobis, n. g.¿) is figured and very 

 unsatisfactorily deseribed as Gl. sulcatüs. All that is stated is — 

 " An oval disk on the breast between the pectorals, composed of 

 transverse plates as in the Remora (Echeneis), and a series of simi- 

 lar plates on the broad lower surface of the first rays of the ventrals." 

 No mention of spinous rays : and from the figure published it is 

 doubtful if the gill-coverings are visible from below. Adipose dorsal 

 distinct and well developed. Mouth figured as small, subterminal ; 

 with tolerably developed maxillary cirri ; the six other cirri small. 

 "D. 8.— A. 9.— P. 13.— V. 7.—C. 16." 

 The third type is that of his Gl. striatus and apparently his Gl. 

 PECTLTs t opterus, respectively from the Khásya hills and the vicinity 

 of Simia. We have what appears to be the former from Dorjiling ; 

 also another species from the same locality, but in too imperfect 

 condition to permit of a description being taken of it. A fine third 

 species likewise from the Tenasserim provinces. This type may be 

 denominated 



Glyptothoeax, nobis, n. g. Mouth subterminal, large, with a 

 band of card-like maxillary teeth above and below : gill-openings 

 large, and nearly meeting below ; and behind them a pectoral adhe- 

 sive disk grooved longitudinally. Maxillary cirri rather large, with a 

 concealed spinelet at their base ; the six other cirri modérate. Adipose 

 dorsal distinct and well defined ; the anal fin modérate or somewhat 

 large. Dorsal spine well developed, smooth, feebly pectinated behind 

 towards its tip ; the pectoral spines broad and fíat, and strongly pecti- 

 nated behind : a distinct spinous base also to the first ventral ray. 

 Gl. tmlineatus, nobis, n. s. Typical in structure, and of a
