of them are conspicuously larger than in their congeners (Am- 
modytes lancea, Callionymus lyra, and Motella tricirrata). 
1, Ammodytes siculus (Swains.). 
(Smooth Sand-Launce.) 
This species was hitherto known from Sicily only. For de- 
scription see Giinth. Fish. iv. p. 386. 
2. Motella macrophthalma. PI. V. fig. B. 
(Large-eyed Rockling.) 
This species has three barbels, one at each of the anterior 
nostrils and one at the chin. It is distinguished from specimens 
of the same size of the other three-bearded species by its large 
eye, the diameter of which, in the specimen obtained, is as long. 
as the snout, one-fourth of the length of the head, and much 
longer than the width of the interorbital space. The teeth of the 
mandible are very unequal in size, some being canine-like. The 
anterior ray of the rudimentary first dorsal fin is about as long as 
the eye. D.55. A. 55. Back with narrow brownish cross bars. 
Three inches long. 
The figure represents the specimen of the natural size. For 
the sake of comparison the figure of the head of Motella tri- 
cirrata (B') has been added. : 
3. Callionymus maculatus, Bonap. Pl. V. fig. A. 
(The Southern Dragonet.) 
This species is common in the Mediterranean ; but it has been 
also observed on the coast of Norway. It is easily recognized by 
the shortness of the snout relatively to the diameter of the eye.

2.6.) 10. Ay ®, «das dak, BOs 
Body as deep as broad anteriorly, its greatest depth being 
one-half of the length of the head, which is two-sevenths of the 
total (without caudal). Head depressed, broader than high, its 
greatest width being two-thirds of its length. Snout of mode- 
rate extent, though shorter than the eye; lower jaw projecting 
beyond the upper. Eyes very close together, large, their dia- 
meter being two-sevenths of the length of the head. Dorsal 
fins higher than the body ; the second dorsal spine more or less 
prolonged. The pectoral and ventral fins reach equally far 
backwards, to the vent. A series of five rounded blackish spots 
along the lateral line, the last being on the root of the caudal 
fin. Dorsal fins with series of black spots; outer half of the 
anal blackish. A blackish bar below the eye. 
Three specimens, two inches long.
