the Trondhjem Fiord. 443 
whether taken by myself or by the ‘ Porcupine’ Expedition 
of 1869. The example procured is a narrow and very tumid 
form, measuring 15 inch long, 1} inch broad, and 1 inch 
deep ; ; but, if my memory deceives me not, I saw larger speci- 
mens than this in the Trondhjem Museum, and fully the 
size of Davidson’s measurement of his largest specimen. 
Fischer and Cihlert have figured on pl. iv. of the ‘Tra- 
vailleur’ Report a very remarkable triangular form of this 
species, with almost straightly sloping sides and _ straight 
anterior margin, where it is of great breadth. Indeed, 
judging from the figures I should have thought that the form 
might possibly be referable to W. flortdana, Pourtales, rather 
than to W. septigera. 
' 3. Waldheimia cranium, Miiller. 
From 70 fathoms downwards, Trondhjem and Rédberg. 
This species I find generally distributed in the West Norway 
fiords, and I have also taken it in Lang Fiord, Sydvaranger, 
close upon the borders of Russia. 
4. Crania anomala, Miiller. 
In 40-250 fathoms. Specimens from the precipices are 
large. 
TUNICATA. 
As there were several Tunicata which I was unable to 
determine J] sent the animals of this class to Professor 
Herdman, who has kindly examined them and sent the 
following notes. They will be more fully treated of in a 
paper which Professor Herdman has in preparation on the 
Tunicata of Norway. 
fASCIDIA SIMPLICES. 
“Ham. I. Molgulide. 
“1. Molgula eugyroides, Traustedt*. 
“Three specimens from Rodberg, 250-300 fathoms. 
These agree so well with Traustedt’s description and figures 
that I cannot separate them, although MM. eugyroides has “only 
been found previously off Bahia, South Atlantic.
