128 ~~ LIVERPOOL BIOLOGICAL SOCIETY. 
We spent the chief part of our stay at Orotava tow- 
netting and shore collecting. The waters seemed much 
more prolific in surface life than at Grand Canary, and we 
collected a large amount of material, chiefly Copepoda, 
the results of which I have recorded, along with those 
of the other Islands, in a paper recently communicated 
to the Linnean Society. It enumerates sixty-five species 
of Copepoda in all, six of which are new to science, three 
of them requiring new genera. Of the sixty-five species, 
twenty-three are known to British waters, and these 
mostly belong to the Harpacticide. 
The number of species in each family are as follows :— 
Calanide .................. 80 species. 
Gyclopidias ee. eae 
EL Gr DaGticld. 6 mre, eine os 
Ory Copia ae een nl a 
ATLOLLO O10 Comat eke ees 
The new species are :— 
Candace brevicornis. 
C. nigrocincta. 
Acontiophorus angulatus. 
Mecynocera clausit. 
Machairopus santa-crucis. 
Cymbasoma rigidum. 
From a pretty thorough examination of the material 
collected, I am of opinion that the Copepodan fauna of 
the respective Islands, though they are separated by 
considerable distances, varies in quantity rather than 
specifically. For excepting several cases in which only 
one or two of a species were found, and which probably 
indicated rareness of that species, their geographical 
distribution appears to be general amongst the Islands.
