Arrhamphus sclerolcpis. Also this fish has received a new name by Dr, 
Steindachner, viz. Hemirhamphus hrefftii, Sitzgsber. Ak. Wiss. Wien, 1867,

1. Ova of tho Sea- (or River-) Trout, impregnated by the 
milt of the River- (or Sea-) Trout, are developed in the same 
regular manner as if impregnated by the milt of the same spedes. 
The hybrids produced were again fertile. Therefore he comes 
to the conclusion that Mag. Widegren^s opinion with regard to 
the specific identity of these fishes is correct. 
2. Of ova of Charr impregnated by milt of Trout, 30-40 per 
cent, are developed, and many young fish perish after exclusion. 
3. Of Trout-ova impregnated by milt of Charr, only lO per 
cent, are developed, and many of the young fish are misshaped. 
4. Salmon-ova impregnated with Trout-milt yielded 40 per 
cent, young fish, and none whatever when impregnated with the 
milt of Charr. 
5. The ova of a female fish, which appeared to be a hybrid 
between the Trout and Charr, were impregnated by the milt of 
a Trout, but no signs of development were visible. 
Prof. Rasch promises to continue these preliminary experi- 
ments. 
Betropinna richardsonii (Gill) is described by Kner, Novara, Fiseb. p. 318.
