THE GREY GURNARD ( S\V. KNORRHAXEN.) 
TRIGLA GURNARDUS. 
Plate XI, fig. 1. 
Scales of the lateral line about 73 in number 0 , scutiform , reversely linguiform or obovate , armed with spines. Mar- 
ginal plates of the dorsal fin-groove 27 or 28 in number , tuberculated b , but extremely seldom spinous. First two 
or three c spinous rays of the anterior dorsal fin tuber culated. Length of the head to the tip of the opercular flap 
( relatively greater in old specimens than in young ) from 25 to 27 % of the length of the body. Length of the 
snout less than 1 / 2 that of the head. Breadth of the interorbital space , which is slightly concave 1 l , about 1 /f or 1 / 6 , 
and the diameter of the eye about 22 %f of the length of the head. Pectoral fins ( usually longer in the male 
than in the female) considerably shorter than the head °, blackish or gray, with white rays — the 7 or 6 middle 
ones branched once — and with, white spots on the inside. Colouring of the body superiorly gray or brownish 
red, with or without white spots and

Trigla ni gripes , Malm. Vide infra. 
This fish is known by several names in the western 
islands: its most common name in Bohuslan is Knot, 
in Stroinstad it is called Halhos. The name Knorr- 
hane (“purring cock”), which is really Scanian, has 
arisen from the circumstance that, when drawn out of 
the water, the fish makes that purring sound the origin 
of which we have explained above. 
The Grey Gurnard occurs along the whole of the 
west coast of Scandinavia. In the Baltic, according to 
Nilsson, it penetrates to the coast of Blekinge, and, 
according to Winti-ier, to Christianso (N. E. of Born- 
holm), though it is rare there, but fairly common west

a From 72 to 76, according to Steindachner. 
6 At least the anterior: in full-grown specimens all. 
c Sometimes the fifth ray too, according to Tillier. 
d More so in young specimens. 
e From -/ 13 to 2 / n of the length of the head to the tip of the lower opercular spine, according to Steindachner. According to our 
measurements varying between 17 and 21 %, i. e. about 17 % (in young specimens) and from 18 to 2 1 '% (in old), of the length of the head 
to the point of the opercular flap. 
/ According to our measurements varying between 27 % (in a specimen 70 mm. long) and 20 (in a specimen 300 mm. long) of 
the length of the head to the point of the opercular flap. 
3 From 4 / 19 to 4 / 24 of the length of the body, according to Tillier. These fins too, are comparatively longer in young specimens than 
in old, but their tip never extends behind the middle point of the length of the body.
