154 FISHES. 



a blood-red; red lines on the first dorsal; lines of salient points 

 forming an H on the nape of the neck, &c. 



Some species are also found in fresh water ; such is the Gob. fiu- 

 viatilis, observed by Bonnelli in a lake in Piedmont, smaller than 

 the niijer, blackish, without the free pectoral filaments, and a black 

 spot above the branchial aperture. . A large one is obtained in the 

 environs of Bologna, the G. lota, Cuv. ; brown ; blackish veins on 

 the cheek; a little blackish spot on the base of the pectoral, and an- 

 other on each side of that of the caudal. 



Among the Gobies foreign to Europe, we may observe the G. ma- 

 crocephalus ; Cottus macroeeph.. Pall., Nov. Act. Petrop., I, pi. x, 

 f. 4, 5, 6, on account of the extreme length of its head. The G. 

 lanceolatus, Bl. 33, 1; G. bato, Buch., pi. 37, f. 10; Eleotris lan- 

 ccolata, Bl., Schn., pi. xv, which we call the Gobius elongatus, on 

 account of their elongated form and pointed caudal*. The 



Gobioides, Lacep. 



Only differ from the Gobies in the union of their dorsals, which form but 

 one. Their body is more elongated -j\ 



T.enioides, Lacep. 



These, with the single dorsal of the Gobioides, have a still more elon- 

 gated body. Their physiognomy is extremely singular; the upper jaw is 

 very short ; the lower, elevated and every where convex, ascends in front 

 of it, both being armed with long hooked teeth ; the eye is almost re- 

 duced to nothing, and is completely hidden under the skin. The cavity 

 of the mouth is occupied by a fleshy and nearly globular tongue, and there 

 are some small cirri beneath the lower jaw. 



But one species is known, the Ttenioide Hermannien, Lacep., 

 which lives in the mud of ponds, in the East Indies J. 



Bloch, Schn., p. 63, very properly separates from the whole genus 

 Gobius the 



Periopiitalmus, Schn. 



Which have the entire head scaly; the eyes are brought quite together, 

 and provided at their inferior edge with an eyelid which can be made to 

 cover them, and the pectorals are covered with scales for more than half 

 their length, which give them the appearance of being attached to a sort 

 of upper limbs. Their gills being even narrower than those of other 



* Among these species foreign to Europe, we may unhesitatingly place the Gobius 

 Plumieri, Bl. 175, 3;— G. lagocephalus, Pall. VIII, pi. 11, f. 6, 7;—G. Boddurti, Id. 

 lb., pi. 1, f. 5; — G. ocellaris, Brouss. Dec, pi. 1 1 ; — G. bosc, Lacep. II, xvi, 1, or G. 

 viridus-pallidus, Mitch, op. cit. I, 8, or G. alepidotus, Bl., Schn.; — G. Rvssclii, Cuv., 

 Russ. I, 53; — G. giuris, Buchan., pi. xxxiii, f. 13; Russ. 1, 50; — G. chungua, Buch. 

 pi. V, f. 10; — the Bostrijche chinois, Lacep. II, xiv, and many new species to be de- 

 scribed in our Hist, des Poissons.

X It is the Ctepola cacula, BL, Schn., pi. liv,from a drawing by John; the Tirnidide 

 hirmamiiev, Lacep. II, six, 1, from a Chinese drawing; and the Gobioide rubkunda, 

 Bueh., pi. v, f. 9.
