TWO NEW SPECIES OE THE J^HOKONIDEA.

Affiiiities.^ — There can be no doubt that this animal is a 
species distinct from Phoronopsis albomacnlata, the 
other member of the genus. The hitter, from South Africa, 
described by Grilchrist (7), was 18 mm. long, and the tube 
was attached by one side to its substratum witli the two 
ends near together. The lophopliore was horseshoe-shaped 
and carried 126 tentacles. There were 94 fascicles of longi- 
tudinal muscles. 
The comparatively -enormous size, greater number of ten- 
tacles and different habit of life of Phoronopsis harmeri 
are, I venture to suggest, minor points of difference, and the 
shape of the lophopliore and the possession of a far lai'ger 
number of muscle fascicles are the moi-e important systematic 
characteristics. 
In conclusion I should like to thank the Rev. G. W. Taylor, 
F.R.S.C., Cura, tor of the Marine Laboratory, Departure Bay, 
for his courte.sy and help during my visit. 1 also wish to 
express my thanks to Dr. Harmer, F.R.8., for kindly giving 
me assistance, especially with regard to literature, and to 
Dr. ^larett Tims for his help and interest throughout.
