30 ORCHESTIIDJE. 



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. Bott<%, 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.
