(I'ead June 8, 1020. Puhlishcd July 12, 1020.) 
In the collection of freslnvater Ain})hipo(ls wiiich has accumu- 
lated as one result of a number of trips made into different parts 
of this State, are a number of specimens taken at many localities, 
closely akin to the form recently described by (Jhilton in this 
Journal, and named by him Neonipharffus wcsfraJis, (]92o). 
The specimens which Chilton examined Avere some which had 
been taken by myself, early in the winter of 1022, from a small 
spi'ing in a valley just immediately east of Darlington Railway 
Station. In the first instance they were sent to Dr. Caiman of 
the British Museum l^y Mr. Glauert, tf> whom I had submitted 
Uie specimens for identification. As Dr, Chilton notes, these 
S])ecimens were returned to Perth and forwarded to him in 1023*. 
These first specimens Avere Avhite in colour and slightly trans- 
lucent in life, rarely with faint traces of vi'stigial eyes occurring 
immediately behind the base of the first antenna; in preserved 
specimens these vestiges are no longer to be made out. 
Specimens olitained later, from other creeks emptying into the 
Helena River beloAv Darlington, as well as from springs and creeks 
discharging into the ^fundaring Reservoir, wliile closely resemblin.e 
in many points, the bleached sjiecimens first obtained, differe<l 
visil)ly in colour, varying from broAvnish yellow to pink. In these, 
* Tlie small collection Avas supplementc<l, as I learn from Mr. 
Glauert, by specimens which the latter had himself collected in 
the meantime-
