180 FISH GALLEUY. 



Ramsgate, Lowestoft, and Grimsby, but many of the Soles that 

 come to the London market are caught off Portugal and Morocco. 

 Sand Sole. The Sand Sole, Solea lascaris, 786, differs from the Common 

 Sole in being paler in colour after death, in having small black 

 specks instead of large black blotches, and in the anterior nostril 

 of the lower side being large and conspicuous and fringed 

 internally. There is a black spot with a yellow margin on the 

 pectoral fin. The Sand Sole is sometimes called the Lemon 

 Sole, but the fish that is sold in London as the Lemon Sole is 

 the Smear Dab, Glyptocephalus microcephalus, 776. The Thick- 

 back, Solea variegata, 787, is smaller than the Common Sole, 

 and the mouth is straight and more terminal. The colour- 

 markings consist of five dark bands on a reddish-brown ground ; 

 the pectoral and pelvic fins are rudimentary. The Solenette 

 Solea lutea, 788, is distinguished by the mouth being much 

 curved and by the dorsal fin commencing on the extreme anterior 

 end of the snout. There are dark blotches on a yellowish ground, 

 and the dorsal and anal fins have a few scattered black fin-rays. 

 The Solenette does not exceed five inches in length. 



The genera Synaptura (789 and 790) and Cynoglossus (791, 

 fig. 84 E) differ from Solea in the dorsal and anal fins being 

 confluent with the caudal fin. In Synaptura the eyes are on the 

 right side, the upper in advance of the lower ; in Cynoglossus the 

 eyes are on the left side, there are no pectoral fins, and the upper 

 part of the snout is produced backwards into a hook. The fishes 

 of these genera occur in the tropical seas of the Old World. 



Gobiiformes (Gobies) . 



The division Gobiiformes is a small division of the suborder 

 &canthopterygii and includes a single family, the Gobiidas ; the 

 species of the family are numerous, and the fishes are mostly 

 marine and of small size, although some species of Eleotris grow 

 to two or three feet in length. The pelvic fins are thoracic in 

 position and consist of one feeble spine and four or five branched 

 rays ; they are in many species united to form a sucking disc.
