MARINE BIOLOGICAL STATION AT PORT ERIN. 21 
research could not have been carried out at any biological 
station which did not possess a fish hatchery, and there 
are many other problems in connection with the biology 
of fish larve which could be undertaken with advantage 
at Port Erin. 
‘* During the Easter vacation I fixed a considerable 
quantity of whelk material for histological purposes, in 
connection with the L.M.B.C. Memoir, ‘ Buccinum,’ on 
which I am now engaged; and whilst cutting out the 
renal organs of certain specimens, I noticed numerous 
exceedingly small white bodies. Sections through the 
renal organ, made on my return to Belfast, showed that 
these bodies were Sporozoa, and apparently an unknown 
species. I have now been able to make out from this 
material a considerable number of the stages in the life 
history, and hope to publish a preliminary statement at 
an early date. The parasite is of considerable size when 
full grown, and is, in all probability, a Coccidian.”’ 
Dr. W. D. Henderson, now Head of the Zoology 
Department in the University of Bristol, while 
occupying the Manchester University Work-Table in 
April was engaged in a research on the development of 
the head in the Plaice. Dr. Henderson reports to me 
that the work is not completed, but that his material 
promises to furnish some interesting results, and that he 
proposes to communicate the finished work to the Royal 
Society of Edinburgh. 
Mr. Andrew Scott reports that several additions to 
the local fauna have come into his hands during the year, 
and one of the most interesting of these is the curious 
little burrowing Crustacean, Callianassa subterranea, 
which is intermediate between the hermit crabs and the 
lobsters. A freshly severed chela or great claw, which 
must have been recently eaten, was found in the stomach
