Tlie fi.sh for which Pallas intended the name of /S". cmtumnalis, is 

 perfectly unknown ; it is evidently a migratory Troiit, or perhaps a 

 young Salmon. The specimen lahclled S. autumnctlis in the Berlin 

 Museum, is a Charr from Kamtschatka (p. 144). 



31. Salmo spectabilis. 



Salar spectabilis, C'uv. ^- Tal. xxi. p. 340. [On Salar spectabilis 

 (Heck. S,- Kner), see p. 85]. 



Valenciennes gives the following descrijition of this species with- 

 out distinctly naming the locality where it was obtained : — 



Vomerine teeth in a doi;blo series. It is distinguishable from 

 all our Trouts by its fusiform and more regularly elliptical body. 

 Its head is about one-fifth of the total length. The cleft of the 

 mouth is moderate, a little less than one-third of the length of the 

 head. The muzzle is pointed. The two jaws are equal. The 

 praeoperculum is regularly rounded. The eye is small ; its diameter 

 is contained six times and a half in the length of the head. The 

 fins are small. The scales are more apparent, or, rather, less hidden 

 by the mucositj' of the skin. 



There are 130 longitudinal series. The colour is steel-blue on 

 the back, fading into silvery on the sides. The under surface of the 

 belly and throat is dull-green. The sides and cheeks are scattered 

 over with black spots. The largest of three specimens is 16 inches 

 in length. 



32. Salmo lepechini. 



Pal'jfe, Lepechin, Reise Russ. Reich, iii. p. 229, taf. 14. fig. 2. 

 Salmo lepechini, L., Gni. i. p. 1374 ; Cuv. ^ Val. xxi. p. 342. 



This fish is said to be found in the torrents of the Eussia^ pro- 

 vince Olonczk. The figure given by Lepechin is probably taken 

 from a sldn, and does not assist us in defining this species, if, indeed, 

 it be distinct. The skin in the Berlin Museum from PaUas's Col- 

 lection, named S. lepecliini, and mentioned by Valenciennes, is inde- 

 terminable. 



XI. Trout from the laTce Goulxha, near Erivan, Armenia. 



Pallas (Zoogr. Ross.-As. iii. p. 346) mentions a trout of that lake 

 from notes made by Giildenstadt ; he erroneously considers it to be 

 identical with S. Jmcho. : — 



D. 11. A. 10-11. Csec. pyl. 70. Vert. 54. 



Male entirely of a ferniginous tint, with a very indistinct silvery 

 lustre on the sides, and with very few black spots, scarcely distinct 

 except between the pectorals and ventrals ; throat white. Female 

 brown above and on the fins, below and on the sides white, varie- 

 gated on the sides, as also on the opercles and dorsal fin, with round 

 black spots, 3 lines in diameter, and placed far apart. Scales 

 scarcely 1 line broad. Flesh red. Ova orange-coloured, 2^ lines 

 in diameter. Total length 1 foot 7 inches.
