ON RECENT POLYZOA. 541 
In his Report on the Polyzoa of Queen Charlotte Island, ‘ Geological 
and Natural Hist. Survey of Canada’ (= Papers in ‘ Annals,’ December 
1882, June 1883, January 1884, March 1884), Mr. Hincks gives very 
elaborate details of the following species :— 
Membranipora variegata, Hincks, Queen Charlotte Island; Cali- 
fornia. ‘Specimens occur in which there are 
two of the pedicellate avicularia at opposite 
sides of the cell instead of the normal one.’ 
acifera, Macgil. Form, multispinata, Hincks, 
‘ Annals,’ Dec. 1882, pl. xix. fig. 4. Loe.:

Report). oc.: Houston Stewart Chan.; Cum- 
shewa, 20 fathoms. 
exilis, Hincks (op. cit.), pl. xx. fig. 1. Loc.:

Sophie, Busk. Form, matura, Hincks (op. cit.), 
pl. xx. fig. 2. ‘Described as M. conferta 
(‘Annals’ for September 1882). I am now

nigrans, Hincks (op. cit.), pl. xix. figs. 2,2a. Loc. :

says Mr. Hincks, ‘armed with more or less 
branching spines’ are— 
cornigera, Busk, Shetland. 
bellula, Hincks, Australia. 
cervicornis, Busk, Victoria. 
cervicornis, Haswell, Queensland. 
Haswell’s name cannot be retained, having been pre- 
viously employed by Busk. I venture to suggest 
the following as a substitute for it.— Hincks. 
Haswellii, Hincks. 
= M. cervicornis, Haswell.

pl. xx. figs. 4, 4a. Loc.: Cumshewa.
