Or Polyzoa about 140 species have been identified by the 
writer from the coast between Cape Cod and Labrador. Nearly 
all these are Arctic or European species, already known. 
They are mostly described in Smitt’s papers on Arctic Bryozoa. 
They are also mostly enumerated by the writer, in a Check-list 
of the Marine Invertebrata of this coast, now in type. The 
following is one of the more interesting new forms. 
e recent determination of so large a number of American 
Polyzoa, confirms the decision already arrived at, several years 
ago, from the study of other classes, that the fauna of northern 
ew England is remarkably arctic and chiefly of northern ori- 
gin, and that the fauna of Greenland is more allied to that of 
Northeastern America than to that of Northern Europe. Ina 
valuable paper* on the Podophthalmous Crustacea of our 
northern coast, just published, Professor S. L Smith has arrived 
at the same results for that group. 
Bugulella, gen. nov. 
Stems slender, dichotomously branched, consisting of single 
series of cells (zocecia), which are connected by short tubular 
joints that. arise medially, from the back and near the distal 
end of the preceding cell, either singly or two together. Zocecia 
elongated, expanded distally, with a large, sunken, elliptical 
frontal area on the front side, close to the end; gradually 
area surrounded by spines. Ocecia subglobular, at- 
tached to the distal end of the zocecia. Avicularia median, at 
the distal end of the zocecia, shaped as in Bugula, Allied to 
Bicellaria and perhaps to Brettia. 
Bugulella fragilis, sp. nov. 
of these the two nearest the distal end are much shorter than 
the other three, which are as long as the breadth of the aper- 
_ ture, and arch over it. Sometimes a median spine is also 
_ present at the proximal edge. Ovicells globose, prominent,
