Habitat. — Largo Bay, not very common. 
Note. — The curious Rhizopods Dendrophrya erecta, Str. Wright, and 
Dendrophrya radiata, Str. Wright, discovered by Dr Wright in low- 
water pools in the Old Quarry at Granton, and described by him in the 
Annals and Magazine of Natural History in 1861, seem to have been over- 
looked by the authors of the " Iu vertebrate Fauna of the Firth of Forth." 
I am indebted to my friend Mr David Robertson for drawing my attention 
to these species'; he informs me that he also has found D. erecta in 
Granton Old Quarry; he has found both forms in low-tide pools at 
Cumbrae. So far as I can learn, there does not seem to be any known 
British habitat for these curious organisms other than the localities here 
referred to.

Habitat. — In surface and bottom tow-net gatherings from various parts 
of the Forth between Inchkeith and May Island, moderately frequent, and 
easily distinguished from the other and commoner Copepoda by the dark- 
coloured plumes and terminal spines of the swimming feet. The only place 
where this species was obtained by Dr Brady and Mr Robertson, as stated 
in the monograph referred to above, was * on very hard ground, and in a 
' depth of about 40 fathoms south-west of the Island of St Agnes, Scilly,' 
where a very few specimens were dredged. The dark-coloured strongly- 
toothed crest on the joint next to and above the hinge of the right antenna? 
of the male is a peculiar and striking object. I have also obtained this 
species in St Andrews Bay, and off Montrose, 20 to 30 miles S.E.
