27 /7 1909, Korsenleiret, Borgenfjord, 1 — 2 m. 3 spee. 1. 16 — 19 



mm. smooth. 

 30 /7 1909, Rolshavn, Borgenfjord, 0—10 m. 1 spee. 1. 20 mm. 



incipient formation; 1 spee. 1. 28 mm. several rows 



of protuberance developed. 

 Ws 1909, Hestnessund, Hittra, 1 spee. 1. 21 mm. smooth: 

 13 /9 1909, Talgøra, near Strømmen, 1 spee. tåken from the 



stomach of a 20 cm. long cod, 1. 20 mm. smooth. 

 V9 1910, Rolsøya, Borgenfjord, 1 spee. 1. 26 mm. rows of pro- 



tuberances developed. 

 It would thus seem that the protuberances of the skin com 

 menee to make their appearance at a lenght of about 20 mm. 

 while at a length of 26 — 28 mm. several rows are developed. 



Lumpenus lampretiformis Walb. 

 This species has only once previously been observed in the 

 fjord, V. Storm having found it in the stomach of cod. It 

 would thus appear to belong to the rarest species in the fjord. 

 I have, however, examined 3 specimens. Two were from Muru 

 viken, 17 /2 1914, 1. 21.2 and 21.8 cm., length of head Vs — l h 

 total length. One was a female with very small eggs. The ven 

 tricles contained remains of annelida and cumacea, with some 

 few foraminifera. A young specimen, 1. 61 mm. was also tåken 

 during dredging operations at Beitstadhoøy, 3 /t 1915. 



Lumpenus maculatus Fries. 

 This species is new to Trondhjem Fjord, and there are 

 altogether but few records of its occurence in Norwegian waters. 

 One specimen was tåken on the 10 /3 1910 in the fjord near 

 Sundnes, (snurrevad, depth 80 metres). The specimen was a 

 ? 1. 104 mm., head about 1 /e of total length. Ovaries small, 

 nothing determinable in stomach or intestine. Brownish spots 

 on the sides, both above and below the lateral line. Cross stri- 

 pes of the same colour running obliquely over the dorsal lin; 

 three vertical cross stripes on the caudal. We also found two 

 specimens of the same species in Muruviken ll h 1914, together 

 with L. lampretiformis. Both were females, total length 13.4 cm. 

 Head abt. Ve total length. Very small eggs in the ovaries ; 

 remains of annelida in the ventricles. Colour patterns in the two 

 species very much alike, L. maculatus, however, having 3—4 cross 

 stripes in the caudal fin, which were lacking in L. lampretiformis. 



Chirolophis galer ita Lin. 

 This species, the crested blenny, is likewise one of the rarest 

 in the fjord. We took a d" 1. 8 cm. in Skarnsund, at a depth 

 of abt. 100 rn. on the 25/ 9 1908. Nothing determinable in stomach.
