the eye is less than one-half of the width of the interorbital space. 

 Fins moderately developed : the pectoral fin terminates at a great 

 distance from the vertical from the origin of the dorsal, and its length 

 is less than one-half of the distance of its root from the ventral. 

 Lower parts deep orange-coloured during the spawning-season, and 

 the lower fins with white anterior margins.

The specific characters of this species are not yet sufficiently 

 pointed out, and it is possible that it is identical with S. nmbla ; 

 indeed both are united by Siebold, whilst Rapp and Heckel do not 

 hesitate to regard them as distinct. None of the authors mentioned 

 has paid any attention to the number of the vertebrae in specimens 

 of the Siilbling. With the materials in our collection we are not 

 enabled to arrive at a decided opinion. The specimens from the 

 Tegern Lake are very young, and we are not certain whether they 

 should not be referred to S. umhJa ; and as regards the specimens 

 from Lake Wetter, a direct comparison with the true Siilbling may 

 show that it is a distinct species altogether, differing from it by 

 having the body more elevated, and the scales larger (190 transverse 

 series).

 Body slightly compressed and elongate, its greatest depth being 

 one -fifth or one -sixth of the total length (to the end of the middle 

 caudal rays). The length of the head equals the height of the body 

 in mature specimens, but is somewhat moi'e in immature ; it is two- 

 ninths or one -fifth of the total ; it is rather less than, or equal to, 

 one-half of the distance between the snout and the vertical from the 

 origin of the dorsal fin. The maxillary extends but little beyond 

 the orbit in the fully adult fish. The ej-e is one-half, or rather less 

 than one-half, of the width of the interorbital space. The length 

 of the pectoral of the mature fish is more than one-half of the dis- 

 tance of its base from the root of the ventral ; in immature speci- 

 mens its length is considerably less. The length of the longest ray 

 of the dorsal is much less than that of the pectoral, and three-fifths 

 or one-half of the length of the head ; the length of its last ray is a
