County of Dublin, and is numerous on the shores of 
Plymouth Sound, under Mount Batten, where Talitri 
may also be taken ; but the latter appear to occupy a 
higher coast-line, where the soil is sandy. 
The eggs of this species are of the same colour as 
the female, and, after exclusion, the young are carried 
about by the mother beneath the body. 
Professor Kinahan informs us that Mr. Williams, of 
Drogheda, has observed them in Mornington Bay to be 
phosphorescent. 
Several specimens have been sent to us as Orchestia 
Botta , M.-Edw. (a native of the Red Sea), but, taking 
into consideration the fact announced by Rathke, that 
the dilated and tubercular character of the posterior pair 
of legs is only the result of age, we have considered that 
O. Bottce, as a species, is at least doubtful, and, at all 
events, the supposed British form is only that of a 
youthful Orchestia of the present species.
