retain a connection with the central gastric cavity by means of 

 channels along which the sex-cells pass on their way to the 

 exterior. These channels, I take it, are the main j)'^f'Ssages of 

 connection between the gastric pouches and the central gastric 

 cavity referred to in the above paper. 



L. Agassiz makes no reference, either written or by figure, to 

 the ridges of epithelium which form the boundaries of the 

 " gonadial grooves " in the above account. 



It should be noted that it is within the limits of these grooves 

 that it is suggested the sex-cells pass on their way to the exterior 

 at the period of extrusion, and that it is only these parts which 

 form the primitive gonoduct by a pinching-off from the arch- 

 enteric cavity.]

A small series of fresh- water fishes collected in Corea by Mr. M. 

 P. Anderson and presented to the British Museum by His Grace 

 the Duke of Bedford, K.G., is of considerable interest, as of the 

 eleven species represented, no less than seven are new to science, 

 some of these extending the range of genera previously known 

 from China or Japan. The specimens are from two localities, 

 viz., Chong-ju, Chung-Chong province, and Kimhoa, 65 miles 

 north-east of Seoul ; from the latter examples of only two species 

 {iSilurus bedfordi and Liohagrus andersoni) were obtained. 



Cyprinid^e. 



1. Oarassius auratus L. 



2. PSEUDORASBORA PARVA Schleg. 



3. Barilius platypus Schleg. 



4. Leucogobio strigatus, sp. n. (Plate II. fig. 2.) 



Depth of body equal to or a little more than the length of 

 head, which is 4 in the length of the fish. Snout a little longer 

 than eye, the diameter of which is 4 in the length of head ; 

 interorbital width 1^ to 3 in the length of head. Mouth oblique ; 

 barbels small. Dorsal 10, with 7 branched rays ; origin equi- 

 distant from tip of snout and base of caudal and above that of the 

 ventrals. Anal 9, with 6 branched rays. Pectoral not reaching 

 bhe ventrals. Caudal forked. 36 to 38 scales in a longitudinal
