Et desvmrre i hpi Grrad mutileret Exemplar af denne 
forst af Bovallius beskrevne Form toges under Expeditio- 
ns lste Togt ved det ydre Afhseld af Storeggen (Stat. 
24) paa 90 F. D. 
Bovallius bar for denne Form opstillet en ny Slaigt, 
s °m dog kun svnes mig lidet at * skille sig fra SI. Portunus . 
Af de bekjendte Arter af denne sidste Slsegt synes den at 
komme nmrmest P. longipes Roux, der ligeledes bar den 
bagerste Sidetand paa Rygskjoldet ussedvanlig stmrkt for- 
beriget. 
Det erholdte Exemplar var ligesom det af Bovallius 
beskrevne en Han og stemmede i alt vsesentligt overens

A. specimen of this form, first described by Bovallius, 
was taken — we are sorry to say in a highly mutilated 
condition — on the 1st cruise, off the outer slope of the 
Storeggen Bank (Stat. 24). at a depth of 90 fathoms. 
For this form, Bovallius has instituted a new genus, 
which, however, in my judgment, would appear to differ 
but slightly from the genus Portunus. Of the known species 
belonging to the latter genus, the animal in question ap- 
parently approximates closest P. longipes Roux, which has 
likewise the most posterior of the lateral teeth on the 
carapax unusually produced. 
The specimen obtained, like that described by Bovallius, 
was a male, agreeing in all essential characteristics with
