1898-1902. No. 25.] FISHES. 



Aug. 30, 1901. The head of the Gaasefjord. 8 metres, small stones and 

 clay with brown algae. 1 specimen, a*, 62 mm. 



Aug. 4, 1902. Gaasefjord, north of the peninsula, 1015 fath. 1 spe- 

 cimen, 29 mm. 



Thus the collection contains 14 specimens in all, the largest male 

 among them being 77mm., while the largest female as usual measures rather 

 more, namely 91 mm. In 6 of them, the number of fin-rays was D 1 . 9, 

 D 2 . (19) 20-21, A. (14) 16, P. 18. 



The development and distribution of the dermal plates is, as usual, 

 subject to great variation. The bony shields of the lateral line, for in- 

 stance, generally extend almost to the base of the caudal fin, but some- 

 times only to the end of the second dorsal fin or even less. The parie- 

 tal protuberance always has a more or less distinct ledge in front. 



In a male, 61.5 mm. in length, the genital papilla is of the fol- 

 lowing particulars : the base is 5 mm. long, clavate, expanding distally, 

 directed a little obliquely backwards ; its point is 4.5 mm. long, awl- 

 shaped, and forming an angle with the base, so that its direction is 

 backwards, almost parallel with the belly. 



Triglops pingelii REINHARDT. 



July 30, 1900. The entrance to Stordalen, Havnefjord. 1 specimen, 81mm. 

 This specimen has the following number of rays: 



D. 37 (DUO, D a .27), A. 26, P. 20. 



In specimens from West Greenland, the following number of rays 

 occur in the unpaired fins: 



D. 34 36(D!. 1113, D 2 . 23-25), A.23-25. 

 In specimens from East Greenland the numbers are as follows: 



D.34-37(D 1 .ll-12,D 2 .23-26),A.23-27. 

 In two specimens from Iceland, I have found the following numbers: 



D. 31 (D 1 . 10, D 2 . 21), A. 21; 

 and in three specimens from the Faroe Islands: 



D. 31-32 (D 1 . 10-11, D 2 . 21), A. 20-21. 



In a fourth specimen from the Faroe Islands there were even only 

 27 rays in the dorsal fins, DUl and D 2 .16. 



Thus the number of rays in the unpaired fins becomes smaller in 

 southern regions 1 . 



1 Triglops murrayi, described by GUNTHER (Proc. Roy. Soc. Edinb. XV, 1888, 

 p. 209) from the north-west of Scotland, of which the small number of rays ( 

 in the second dorsal fin was said to be characteristic, is therefore scarcely m 

 than a southern form of T. pingelii.
