A history of the British sessile-eyed Crustacea .

As yet we know not the form of the male animal;it may be similar to that Vvhich we figure as the female,but had not Miiller, Rathke, and Lilljeborg described thefemales of Tanais as resembling the male, we should havesuggested that these species were females of Tanais, forit is a singular fact that although of the latter genus wehave examined some hundreds of individuals, we havenever yet seen one possessing the features of a female.* * We are bound, however, in tliis place to recall attention to Rathkesfigure of his Crossurus vittatus \vith a large incubatory pouch filled withlarge eggs.
