CARINELLA ANNULATA. 203 



This species can be only imperfectly described at present, as its distinction was not 

 recognized on the sole occasion on which it was seen alive. The specimen found at Herm was 

 of a rose-pink colour in front, pale posteriorly. There are no lateral fissures on the head. The 

 mouth lies on the ventral surface some distance behind the tip of the snout, and in the preserved 

 specimens forms a small puncture or dimple. The worm appears to attain the length of four or 

 five inches. 



Numerous specimens of an elongated example of the Anopla without lateral fissures occur 

 in a collection brought by the Rev. L. Guilding from the West Indies, and now in the British 

 Museum. All have a peculiarly corrugated and thickened anterior end, and a small round mouth 

 like a puncture. Some measure about fifteen inches long. 



Family III. — Carinellid^). 

 Genus X. — Carinella, Johnston, 1833. 



Before the time of Dr. Johnston the typical animal of this genus, the Gordius annulatus of 

 Montagu, had not been sufficiently distinguished from its congeners ; and though he named the 

 species in ignorance of the prior observations of Montagu, yet his generic title is more appro- 

 priate than that of MecMia, in favour of which the original name was suppressed. The latter 

 term was given to one of the Lineidse, while the type here is totally different. Carinella, as its 

 originator says, labours under the disadvantage of being a name which the scholar may " in vain 

 puzzle himself" to find out "from what, and whence, it is derived." At first sight it seems to 

 be a diminutive of carina, a keel. 



Generic character. — Body elongated, tapering from the front backwards. Snout wider than 

 the rest of the body, bluntly rounded anteriorly. Mouth sometimes small.

Specific character. — Eyeless, with a white patch on the snout. Body rounded, of a rich red 

 colour, striped longitudinally and banded across at somewhat regular intervals by white belts. 

 Occasionally pinkish throughout.
