represent the mandibles ; and hence I am not sure whether the 

 species should not range under the genus Raphignathus of 

 Duges. 



The legs are about equal and alike; the fourth and sixth 

 joints are large and swollen; the seventh is the largest and 

 tapers abruptly at the middle, like a claret bottle ; the tip forms 

 «, little round disk, whence diverge a pair of curved hooks, with 

 plain edges, but two-toothed at the tip, or rather having a pro- 

 minent tooth over the tip (fig. 4). All the joints are well fur- 

 nished with straight bristles, the sixth having one much longer 

 and stouter than the rest. The limbs are set in two series, the 

 first and second originating close together, but remote from the 

 third and fourth, which are also contiguous to each other. 



Several specimens of this little Mite, I have found in one of 

 my older vessels of sea-water. They climb up the glass sides, 

 among the flocculent vegetable matter that is deposited on the 

 glass. I afterwards found it among bushy sea-weed at Ilfra- 

 combe, in August. 



The specific name is from voyro?, the back, and o>y^, the eye.

c"^ found another specimen of this marine Mite in one of my 

 aquaria, among weed from Ilfracombe. It was jj th of an inch in 

 length, the body opaque or only subpellucid white, tinged in- 

 ternally with pale red ; the median white line very conspicuous. 

 Strongly conspicuous also were two lateral black eyes, which ex- 

 actly agreed with those of H. rhodostigma, and a third orbicular 

 eye also black, close behind the rostrum. Neither of these eyes 

 was visible in the specimen I before examined. The shape of 

 the body agreed more with that of H, rhodostigma, and, as in 

 that species, the anus here was papillary and terminal. This 

 specimen appeared to be a male. 



A single Vorticella of a rather shallow bell was attached to the 

 body, and the limbs carried several Acinetcs, perhaps of the same 

 species. They had a cylindrical body set on a very slender 

 stem ; the body cut into very distinct annuli, and bearing on its 

 two anterior angles pencils of short capitate setse (PI. VIII. fig. 6). 

 Total length 7^0 th of an inch.
