BRYOZOA FROM FRANZ-JOSEF LAND. 81 
The operculum of P. Skenez is longer in proportion to the width 
than in most of the typical Porella such as P. levis, Flen. The 
mandibles have the characteristic diagonal bars and a raised line 
below.

As it seemed doubtful whether the Eschara elegantula of 
Smitt is the same as the L. elegantula* of d’Orbigny, I stayed 
in Paris, en route, in order to examine the specimen described by 
d’Orbigny, and that I found is what Busk has since described as 
Porella perpusilla. 
It should not be overlooked that the specimen with which 
Smitt made the comparison was, according to Smitt, marked 
“ Eschara fascialis.’ The specimen from which no doubt 
d’Orbigny’s description was taken is not so marked, so that I do 
not gather what Smitt examined. 
D’Orbigny’s original specimen No. 138622 of Hschara elegan- 
tula from Newfoundland, now in the Musée d’Histoire Naturelle 
in Paris, is composed of cylindrical branches between one and 
two millimetres in diameter, with the ordinary avicularia much 
smaller than in the more common P. saccata, but the mandibles 
of both are similar (compare Pl. 10. figs. 11, 12,13). In the 
Paris specimen already alluded to the avicularia are sometimes 
* Eschara elegantuia, & Orbigny, Pal. Frang. vol. v. p. 102.
