Natural History of East Finmark. 119 
Avicularia I have seen sparingly developed, but only on 
Spitsbergen specimens and on one side of the zocecium, as 
figured by Smitt. Nordgaard, however, illustrates a zocecium 
with two avicularia, which were developed on a specimen 
from a “ place unknown.” 
Nordgaard has referred the Mucronella prelucida of 
Hincks * with a ? to this species. With respect to the Queen 
Charlotte Islands type specimens I think that there may be 
some doubt, but I am very much inclined to refer the 
St. Lawrence form to M. sincera. I have a specimen from 
that locality the zocecia of which exactly correspond with the 
left-hand zocecium of Hincks’s illustration ; but the oral lip 
processes are none of them truncate as drawn on the other 
three occia. I consider my specimen to be M. prelucida (of 
St. Lawrence), a variety of M. sincera in which the zocecia 
are shorter than usual.

Varanger Fiord, in 120-150 fathoms, on shell of Astarte, 
and Nordgaard has kindly sent mea specimen from Sver- 
holt. This last specimen is developed on Hornera lichenoides, 
a habitat which the species seems especially to affect, as fine 
examples were dredged upon it in 175 fathoms off Hare 
Island, Disco, Greenland, by the ‘ Valorous’ in 1875. 
It would seem that Smitt a: first included more than one 
form under the term “forma Jladiata,’ since a specimen 
received from him just after he had finished his work is 
undoubtedly a variety of Escharella ventricosa with produced 
lip; but I think that there can be no doubt that his figure 
176 represents the species which was subsequently named by 
Hincks Phylactella (?) grandis. 
It would be quite possible that Hscharella abyssicola might 
be mistaken for this species. There is a very general resem-
