Tiiis fish differs fruin the Acipenser stiirio, the only other British 

 species of sturgeon, in having the extremity of the snout much 

 broader than the diameter of the mouth, — the keel of the dorsal 

 plates but slightly elevated, — and the cirri situated much nearer to 

 the tip of the nose than to the upper lip. For a representation of 

 the head see the accompanying Plate. No. I. 



Gobius uniptcnctaUis. (Parnell.) 



This species of Goby is common on the coast of Devon, rare in 

 the Solway Frith, and occasionally met with in the Frith of Forth. 

 It grows to three inches and a half in length. The back is of a 

 reddish-brown crossed with a few short dark lines ; the belly, ven- 

 tral and anal fins, are of a pure white. The first dorsal fin is com- 

 posed of six rays, the second of eleven rays, the last rays being 

 shorter than the first. The tail is even at the end. Between the 

 fifth and sixtii ray of the first dorsal fin is a large dark spot which 

 is always constant; from which circumstance the author has pro- 

 posed tlje name of unipunctatus. This fish perhaps is nearer allied 

 to the Gobius minutus than to any other ; but the dark spot on the 

 firstdorsal, and the tail being even at the end, will readily distin- 

 guish it. 



Gobius ulbus. (Parnell.) 



This fish, in the month of June, is common in the Solway Frith, 

 and is evidently the fry of a large species. Its length is about two 

 inches. The body nearly transparent ; the head large ; the gape 

 wide ; the teeth small and sharp, placed in one row in each jaw. 

 The numbers of the fin rays are — first dorsal 5 ; second dorsal 13 ; 

 ventral 13; anal 13; caudal 12. The terminating rays of the 

 second dorsal and anal fins are the longest. The presence of only 

 five rays in the first dorsal fin is sufficient to distinguish this fish 

 from every other of the same genus. 



The .iccompanying plate No. I. represents the two new species 

 together with the other species of Gobius previously distinguished. 



Dr Parnell at the same time exhibited several specimens of 

 fishes hitherto unnoticed on the coast of Scotland. 



Trigla Blochii (Yarrell.) Specific character. — A black spot on the 

 first dorsal fin ; the dorsal ridge and lateral line strongly ser- 

 rated. Frequent. July.
