424 APPENDIX. 



the tips of the ventral fins are dark red, and the digitated appendages are 



banded with white ; the points of the anal rays are white ; and the tail is 

 dark, with white cloudy spots ; at the base of the first dorsal ray is a black 

 spot. 



Obs. — Not being able, at this moment, to consult the original description 

 by Brunnich, of his Trigla Adriatica, I must leave it to others to determine 

 •whether modern ichthyologists are correct in considering it the same as the 

 lineata of Bloch, and of Linnaus. In the mean time, however, the 

 species above described is clearly distinct from the lineata of Bloch and 

 of Cuvier, who both agree in assigning to their species a double series of 

 spines on the lateral line, and ol tricusp2date spines on the dorsal series, or 

 that which margins the base of the dorsal fins. Now, both of these series, 

 in the present species, are always composed of simple spines, without any 

 serrature or division whatever. In their species, also, the ventral fin has 

 but 13 distinct rays, whereas, in this, there are invariably 16. This 

 number agrees with what Gmelin (who, no doubt, copies his account from 

 Brunnich) has assigned to the Adriatka, which he further designates as 

 having the snout retuse, hardly lobed, and not spinous ; all which cha- 

 racters are so applicable to our fish that we have very little doubt of its 

 being the true Adriatica of Brunnich, and consequently distinct from the 

 lineata of Bloch, Cuvier, and Yarrell, who have considered them the same. 

 It may here be remarked that Bloch's figure of his lineata represents the 

 vertical lines or ridges on the abdomen as only extending half-way down 

 the sides, as in T. pini ; so that, if this is correct, it is clearly a diSerent 

 species from the lineata of Cuvier and Yarrell, wliere these ridges extend 

 from the back to the belly, as in our Adriatica. 



TRIGLA Pinu Bloch. 



Transverse ridges of the hody extending half-way down 

 the sides; dorsal spines simple^ the first serrated; 

 a row of smaller spines on the lateral hne ; ventral 

 fin shorter than the pectoral; snout lunated^ the 

 angles with six minute prickles; orbits with two 

 anterior spines.

 Cuculus. Auct. 



Dorsal 9, 18, the last double ; pectoral 10 j ventral 6 ; anal 17. 



Inhabits Sicily. 



M. Cuvier and all our modern ichthyologists assuredly have 

 fallen into error by supposing that the Trigla Pini of Bloch was 

 identical with the Trigla Cuculus, Linn. , of our northern seas. A 

 more attentive comparison of Bloch's figure with the Mediter- 

 ranean fish I shall now describe, has convinced me they are 

 certainly the same. It will also show that the verticillated ridges 

 across the lateral line are not confined, as is generally supposed, 

 to the T". Cuculus of authors. 



Description. — General size and structure much the same as the Cu- 

 culus, but the ventral fins, instead of being longer than the pectoral, as 

 represented by Mr. Yarrell (L p. S4.), are manifestly shorter.* The lateral
