of them are conspicuously larger than in their congeners [Am- 

 modytes lancea, Callionymus lyra, and Motella tricirrata). 



1. Ammodytes siculus (Swains.). 



(Smooth Sand-Lauuce.) 



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. PI. V. fig. A. 



(The Southern Dragonet.) 



This species is common in the Meditei-ranean ; 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. 



4. Gobius Jeffreysii. PI. V. fig. C. 

 D. 6 I 10. A. 9. L. lat. 30. 



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 lapper. 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.
