The Two-spotted Goby has 7 spines in the first dorsal, and a 

 spine and 10 or n rays in the second, in the anal there are a spine 

 and 10 or ii rays, in the caudal there are 15 rays, in the pectorals 

 19, in the ventrals a spine and 5 rays. The dorsals are some distance 

 apart, and the caudal is square. In the lateral line there are from 

 34 to 40 scales. The mouth is oblique, the lower jaw being the 

 longer. There are teeth in both jaws, the longest being in front. 

 The colour is reddish brown, with undulating bands, and a dark 

 band from the eye to the corner of the mouth. The spots are dis* 

 tinct. In length this goby is 2% inches. It swims among seaweeds, 

 near the surface, over rocky ground. 



The Four-spotted Goby has 6 spines in its first dorsal, a spine and 

 9 or 10 rays in its second dorsal, also a spine and 9 or 10 rays in 

 its anal ; there are 13 rays in its caudal, 17 in its pectorals, and 

 a spine and 5 rays in its ventrals. The dorsals are close together. 

 The first dorsal is triangular, the secand spine being much the 

 longest ; the caudal is spatulate. There are from 37 to 40 scales in 

 the lateral line. The body is narrow, the back and abdomen being 

 almost parallel to each other. In colour it is a yellowish grey, with a 

 dark mark descending from the eye. Besides the four dark spots on 

 the body, there are spots on the dorsals, and the caudal and anal 

 have dark edges. In length it is 2 inches. Its only occurrence out 

 of the Mediterranean is in deep water off the Shetlands. 



The One-spotted Goby has 6 spines in its first dorsal, and a 

 spine and 10 or 11 rays in its second dorsal; in its anal it has a

 27 ; in its ventrals 6. In the dorsals the spines are but a trifle 

 higher than the rays, and neither are higher than the body is deep. 

 In the lateral line there are from 60 to 70 scales. The mouth extends 

 nearly to the eye. In the female the eye is more forward in 

 the head than in the male. The colour is yellowish brown, with 

 spots and vertical bands, and is darker in the male than in the
