GENERA AND SPECIES. 8l 



77. galerita, MONTAGU'S BLENNY. A tentacle above the eye ; a 

 black band at the base of the pectorals. 



76. gattorugine, TOMPOT. A tentacle above the eye ; no black band at 

 the base of the pectorals. 



The Butterfly Blenny, like the others, has really one dorsal, but 

 the break in the middle is so marked that it may conveniently be 

 considered as two fins, the first having from u to 12 spines, the 

 second 14 to 16 rays. In the anal there are from 16 to 18 rays, in 

 the caudal n ; the pectorals have la rays and the ventrals only 2. 

 In addition to the tentacle over the eyes there is one on the fore 

 nostril. The mouth extends to the middle of the eye ; in the upper 

 jaw there are from 36 to 40 teeth, and in the lower jaw from 34 to 

 36, there being a curved canine at the back of each jaw. The 

 colour is grey with bands, blotches, and reticulations, and between 

 the fifth and ninth dorsal spines there is a large round black spot 

 with a narrow white edging. This Blenny, which attains a length 

 of 7 inches, lives among seaweeds, feeding upon them and upon 

 crustaceans, molluscs, and small fishes. Of late years it has 

 become rare. 



The Shanny has the first part of the dorsal with n to 13 spines, 

 the second, which is similar in appearance, but longer, having from 

 18 to 20 rays. In the anal, which is just under this, there are also 

 18 to 20 rays ; the caudal has 13 rays, the pectorals have 13, and 

 the ventrals 2. There is no tentacle over the eyes, but on the 

 fore nostril there is a short one divided into 4 or 5 filaments. The 

 mouth is large and extends to below the eye, the upper jaw having 

 from 14 to 20 teeth and the lower from 12 to 16, there being a curved 

 tooth at the angle. In colour the Shanny is generally greenish 

 yellow, banded, blotched, and spotted with black, the fins are 

 yellowish, with black spots, and the anal has a white edging over a 

 black stripe. It is a solitary fish, living in rock pools, driving away 

 its would-be competitors from its hunting grounds, creeping about 

 in and out of the water, jumping up with the aid of its tail, and 

 taking a look round as it stands on its broad pectorals. It feeds on 

 seaweed and on insects, molluscs, and other small animals, and is 

 about 6 inches long. 



Montagu's Blenny has from 12 to 13 dorsal spines, and 15 to 17 

 rays, the second half of the dorsal being higher than the first, and 

 almost semi-circular ; in the anal there are from 17 to 18 rays, and 

 there are n in the caudal, 12 in the pectorals, and 2 in the ventrals. 

 The anal is longer than the second dorsal, but ends at the same 

 distance from the tail. Across the head is an erectile crest, orange 

 in colour, which is united to the dorsal by a row of tentacles. The 

 mouth extends to the back of the eye, and in the upper jaw are 

 from 55 to 65 teeth, there being only 35 to 45 in the lower jaw, 

 which also has a curved canine. This is a small fish, 3 inches long, 

 brownish grey in colour, with vertical bands, bluish white spots, 

 and a line of white blotches from the pectorals to the caudal. It 

 lives in rocky pools and shelters under stony ledges. 



The Tompot has from 12 to 14 spines and 19 to 20 rays in its 

 dorsal, which is united by a membrane to the caudal ; the anal has
