704 ON CRL'STACEA OF THE NEW ZEALAND LAKES. [June 19, 



near Dunedin, and from the Bay of Islands, dredged in 8 fathoms. 

 1 have taken it near the mouth of a little stream at Brighton, 

 in water which was at the time almost fresh to the taste, though 

 close to the sea and affected by extra high tides.

ISTumerous specimens from Lake Waikare. 



This species is vei-y common in all freshwater streams in New 

 Zealand ; I have also taken it in perfectly salt-water in Dunedin 

 Harbour and elsewhere.

One imperfect specimen fi-om Lake Wakatipu (no depth 

 mentioned), and one from Lake Tapu, taken at a depth of 

 700 feet. 



These are both blind, and do not differ appreciably from speci- 

 mens from the underground waters of the Canterbury Plains. 

 This same blind species has also been taken in surface streams at 

 Castle Hill, Canterbury, at an elevation of 2000 feet above the 

 sea ; and more recently Mr. R. M. Laing has brought me specimens 

 from the Longwood Range in Southland. The extension of it& 

 distribu.tion as shown by its occurrence in Lakes Tapu and 

 Wakatipu is very interesting. 



Paracorophium excavatum (G. M, Thomson).

Several specimens from Lake Rotoiti, 5 fathoms, and Lake 

 Waikare (netting among reeds). 



This species was described by Mr. Thomson from specimens 

 obtained from " Brighton Creek (salt-water)." I siibsequently 

 took it in Brighton Creek along with Teiiagomysis novce-zealandioi 

 when the Avater was almost fresh to the taste, and specimens lived 

 in a small bottle of this water for some months. I have specimens 

 also from brackish water at Napier. 



It thus appears probable that the last thiee species are all 

 capable of living in fresh or in salt water ; and the occurrence of 

 Paracorophium excavatum in freshwater lakes far fiom the sea
