a, Represents Carinella'trilineata of the natural size, and in a state of quiescence; b, the'head 

 slightly magnified, and shaded, to show the lateral pale lines ; c, a small portion of the tube. 



The subject of the present illustration has no very obvious 

 relation to any annelide with which I am acquainted, so that 

 I feel myself under the necessity of coining for it a new name ; 

 and I trust the one adopted will be found sufficiently eupho- 

 nical, although the scholar may in vain puzzle himself from 

 what, and whence, it is derived. u Indeed," says Mr. Lindle}', 

 and there is much sense in the saying, " so impossible is it 

 to construct generic names that will express the peculiarities 

 of the species they represent, that I quite agree with those who 

 think a good, well-sounding, unmeaning name, by far the best 

 that can be contrived." 



Carinella trilineata has, among worms, considerable pre- 

 tensions to superior beauty. It is of a hyacinth-red colour, 

 marked with three very distinct pure white longitudinal 

 lines, one running down the middle, and one along each 

 side ; and crossed with numerous lines, of the same colour, 

 which encircle the body, and mark the number of its segments. 

 Besides these more obvious lines, a fainter one is usually ob- 

 servable across the middle of the segments ; and the greater 

 portion of the worm is speckled on the sides with white dots, 

 too small to be seen unless with a magnifier. The ventral 

 surface is of the same red colour as the dorsal, but wants the 

 white line down the middle. The body is soft, vermiform,
