Joly .(1840) to be a testicle_, is, according to v. Siebold, a gland, 
which produces the shell of the egg. He thinks that Artemia 
may be kept distinct from Branchipus by the different and more 
rudimentary formation of its tail, and that under the name 
A. salina several different species, or at least races, have been 
confounded. 
Limnadiidas. 
Limnadia hermanni. The males are hitherto unknown, all described as 
belonging to that sex by Ley dig, Koch, S. Fischer and Chyzer proving to 
belong to otlier genera, especially Estheria. The summit or umbo of the 
shell, distinctly perceptible in the latter, is not distinguishable in limnadia.
