the head. Dorsal spine not serrated, lower than the body ; 

 pectoral spines as long as, but stronger than, that of the dorsal 

 fin, strongly denticulated interiorly. Adipose fin shorter than 

 the anal. Caudal rounded. Dark brown, with a broad 

 blackish band along the side of the body. 

 One specimen, 6 inches long. 



32. Carassius auratus, L. 



Original form, with the colours as in Carassius vulgaris. 

 L. lat. 28. 



33. Gobio nigripinnis, sp. n. 



Although this species lacks barbels, I nevertheless refer it to 

 the genus Gobio — because it has one, and probably sometimes 

 two small pharyngeal teeth in an inner series, whilst Pseudo- 

 gobio has only one series of pharyngeal teeth. 



D. 10. A. 8. L. lat. 37. L. transv. 44/5. 



The height of the body is nearly equal to the length of the 

 head, and one fourth of the total (without caudal). Snout 

 rather compressed, obtusely conical, longer than the diameter 

 of the eye, which is one fourth of the length of the head. 

 Mouth small, inferior ; the lower jaw with the lips well deve- 

 loped, interrupted at the symphysis. Suborbitals (with the 

 exception of the prasorbital) very narrow. The origin of the 

 dorsal fin is considerably nearer to the end of the snout than 

 to the root of the caudal ; ventrals inserted below the hinder 

 half of the dorsal. Caudal forked. Pectorals rather shorter 

 than the head, not extending to the ventral. There are three 

 series of scales between the lateral line and ventral fin. Light 

 yellowish brown, with or without large, dark, irregular, cloudy 

 spots. Nearly all the fins are black, or at least partly black. 

 Generally a vertical deep-black spot on the shoulder. Head 

 and throat of males during the spawning-season orange- 

 coloured. 



Numerous examples, up to 5 inches long. 



34. Gobio nitens, sp. n. 

 Without barbels, like the preceding species, and with the 

 same dentition. 



D. 10. A. 8. L. lat. 35. L. transv. 3£/5. 



The height of the body is one fifth of the total length (with- 

 out caudal), the length of the head one fourth. Snout not com- 

 pressed, obtusely conical, scarcely as long as the diameter of 

 the eye, which is two sevenths of the length of the head. 

 Mouth very small, inferior. Suborbitals (with the exception of
