Note. — Since the above paper was in type, we have received from Mr G. M. Thomson (to whom we 

 are much indebted for valuable material in connection with the study of Australasian Crustacea), specimens 

 of Anaspides from a new locality, "Lake Field, a spot 40 miles from Hobart, Tasmania, at an elevation of 

 about 4000 feet." This altitude corresponds with that of the pools on Mount Wellington, where the species 

 was originally discovered by Mr Thomson.
