1908] Decapod Urustaceans. 29 
norvegieus, M. Sars (Brevik, Langesund and Christiania fiords). 
It was also regularly found, though not so frequently, during 
trawling-operations in the southern fiords (south of Arendal 50—100 
meters, Rosfjord near Farsund 130 —150 meters, and Feddefiord near 
Flekkefiord about 76 meters) and everywhere on soft muddy bottom. 
In the western fiords it is far less common. In the Hillefiord (150 
—170 meters) and Hafrsfiord (35—50 meters) near Stavanger, and 
also in Eidsfiord (100—120 meters) at Gulen north of Bergen I 
have found it occasionally, and Dr. AppkELLør mentions finding it 
in the Byfiord and Hjeltefiord near Bergen as well as in the Bor- 
&undfiord near Aalesund. From these last fiords we have not got 
more than å few specimens. | 
From northern parts of our coast curator NORDGAARD has 
brought home åa few specimens: from Beierfiord, 50 meters, 9 speci- 
mens; Kamstadfiord, 30—90 meters, one small specimen; Mehavn 
1 specimen; and Oxnessfiord, 130 meters, 4 specimens. None of 
these specimens from northernmost Norway had a greater length 
than 60 mm. During the cruise of s/s *Michael Sars” in the 
Northern Sea in 1902, two specimens were taken on 23rd August 
off the south-east coast of Iceland, 64" 177' N. lat., 149 44' W. 
long, 50—80 meters. 
Bathymetrical Distribution: In contradistinetion to its 
nearest relation Crangon vulgaris Which is only exceptionally met 
with at considerable depths Urangon Allmanni has been only once 
found, so far as we know, in shallow water. [11 meters deep, 
near Aalesund (ArrELLør: Decapod Crust.)|. As will be seen from 
the depths mentioned, its most characteristic haunt in Norse fiords 
is the soft muddy bottom in their deeper portions. 
Size: Speeimens as long as 100 mm. (measured from the tip 
of the rostrum to the margin of the telson) have frequently been 
found [Brevik and Laurvik fiordsj. On an average U. Allmanmi 
is considerably larger than UC. vulgaris which in this country, and 
probably in other places as well, is seldom of å greater length 
than 60—70 mm. 
Breeding Season: The largest number of specimens, many 
of which were large females as long as 100 mm., are from the 
eastern fiords (Brevik, Langesund and Laurvik fiords, 80—100 meters)
