had been obtained of each of the first three species and tliree 
of T. crosslandi when I summarised onr knowledge of this 
method of reproduction in 1910 (5). During the summer of 
the next year, 1911, in tlie course of a visit to British 
Columbia, I was able to search for T. gemmipara, and, 
though my success was not so ample as I had hoped, I am 
able to give a fuller account of this specialised form of 
budding than has been published before. I should like here 
to i-ecord my indebtedness to Dr. C. F. Newcombe, of Victoria, 
whose knowledge of the marine zoology of various localities 
in British Columbia was most useful to me in my quest for 
T. gemmipara. 
Trypanosyllis Gemmipara Johnson, 
The account by Johnson, both of the systematic characters 
and of the formation of stolons in this species is full and 
correct. On a few points I find it possible to add materially, 
and it seems necessary to give specific confirmation of 
others. 
Occurrence. 
The single specimen obtained by the Columbia University 
Zoological Expedition in 1896 probably came from the 
neighbourhood of Port Townsend, but unfortunately no data 
accompanied it when it was handed over to Johnson for 
description. From Johnson’s third paper (3, p. 306, footnote) 
it appears that he re-discovered the species in small numbers 
on the Californian coast, but he gives no fui'ther information 
as to its occurrence. 
In the summer of 1911 I obtained this species from three 
separate localities in the N.W. Pacific. Though widely 
distributed it is only to be obtained during the lowest spring 
tides, and is even then comparatively rare in the restricted 
habitat it frequents. I give details as to localities below.
