Salmonim. 
/ Dr. Murie has published a paper entitled Additional Me- 
/ moranda as to Irregularity in the Growth of Salmon (Proc, 
I Zool. Soc. 1870, pp. 30-50) ; it is a continuation of a similar 
j communication in 1868 (see Zool. Record, v. p. 166). The ob- 
j servations are again based on examples which were artificially 
j impregnated and passed through the hands of pisciculturists; 
I they are figured on pi. 2. The author thinks that the migratory 
I species can be retained in fresh water, but not without arrest of 
I development. [Dr. Murie has taken great pains in comparing 
I his examples with descriptions of other Salmonidse ; but detailed 
j descriptions contain of necessity many details characteristic of 
! the individual but not of the species. On the other hand, he 
/ does not notice that unmistakable character of S. solar, viz. the 
number of scales between the adipose fin and the lateral line.] 
Mr. Morton Allport has published a Brief History of the 
Introduction of Salmon {S. solar) and other Salmo7iidce to the
