284 PISCES. 



and by the nostrils opening near the mouth, continued in a groove 

 extending to the edge of the lip, and more or less closed by one or 

 two cutaneous lobules. The teeth have a point in the middle, and 

 two smaller ones on the sides. There are spiracles and an anal fin; 

 the dorsals are placed very far back, the first never being further 

 forward than the ventralsj the caudal is elongated, not forked and 

 truncated; the branchial apertures are partly under the pectorals. 



In some of them the anal corresponds to the interval between the 

 two dorsals: such are the two species of the coast of Europe that 

 are frequently confounded, the 



Sq. canicida, L.; La Grande Roussetie; Bl., 114; Rondel., 

 380; Lacep. I, x, 1. Numerous small spots; the ventrals ob- 

 liquely truncated. 



Sq. calulus, and stellaris, L.; La Rockier; Rondel,, 383; La- 

 cep., I, ix, 2. Fewer but larger spots sometimes ocellated; 

 ventrals cut square. 



A third species from the same locality is marked with black 

 and white spots. (1) 

 In others, all of them foreign to Europe, the anal is attached be- 

 hind the second dorsal, the spiracles are singularly small, the fifth 

 branchial opening is frequently concealed in the fourth, and the 

 nasal lobules are usually prolonged into cirri.(2) Under the name of 



Squalus, properly so termed. 



We include all the species with a prominent snout, under which 

 are placed nostrils neither prolonged in a furrow nor furnished with 

 lobules; there is a lobule on the under part of the caudal which ap- 

 proximates it more or less to the bifurcated form. The old arrange- 

 ment may be preserved which is founded on the presence or absence

 the Raussette of Gunner (Squalus catulus, Gunn. ), Mem. Soc. Dionth., II, pi. i, 

 which appears to be a peculiar species; the Sq. Edwardsii {Edw., 289), under 

 the erroneous name of the Greater Cat-fish, which would indicate tlie Roussette, 

 and which is improperly quoted as the pretended Sq. stellaris,- tlie Sq. africanus, 

 ov galonnc, of liroussonnet (Sh., Nat. Misc. 346). N.B. That the tei-m longitudi- 

 nalihus, gratuitously added by Gmelin, is not correct,- the pretended Sq. cani- 

 cula, Bl., 112, which is a distinct foreign species, unless it be a very uncommon 

 variety of the Catulus.
