blance, especially when the oral lip is more than usually 
produced, as in the specimen figured by Hincks (pl. xxxvii. 
fiz. 1); but that species may be at once distinguished by 
the presence of a bitid denticle within the mouth ; this den- 
ticle is deeply seated and is not shown in the figures given 
by Hincks, though his description is entirely accurate. 
Genus Patmicenzaria, Alder.

The variety bicornis (Busk, Crag Polyz. pl. vil. figs. 6, 7) 
has been recorded by Nordgaard from Sverholt. 
Genus SMITTINA, noy. nom. 
= Snuttia, Wincks, 1879 (partim), nec Smzttia, Holmgren, 1874 (Diptera), 
= Escharella, Smith (partim, nec Zscharella, Gray). 
Type, Smittina Landsborovii, Johnston. 
Some of the following species, as well as others which 
have been described, will not be allowed to remain, in my 
opinion, in this genus, which no doubt Levinsen will revise ; 
such species are those in which there is an absence of the 
“lyrula” or tooth-like process behind the avicularium (which 
is a product of the primary orifice), and there is an absence 
of the “origelles’? at the base of the zocecium, and other 
material differences.

This form or species has has been recorded from the Por- 
sanger Fiord by Nordgaard. 
It is a common form in the Arctic seas, and very generally 
rises in free hollow cups or tubes, often branching. Among 
other characters, this northern form is remarkable for the 
abundant distribution of oval avicularia on the zocecia, as
