lobed character, having a decided inward curve on either side, 

 and a rounded termination overhanging the toes, the most 

 marked departure being the setting of the claws which, 

 instead of tapering off from the shoulder to the end, are 

 recessed so as to form a reversed barb ; the surface of the 

 lorica was also stippled. Length about xsoth in. — J. S.] 



(xlv) Distyla ichthyoura (n. sp.) Brighton. [The most 

 distinctive character in this form, is the fish-tailed append- 

 age to the posterior end of the lorica, which extends over 

 half the length of two rod-shaped toes, each toe possessing a 

 one-shouldered tapering claw. Anteriorly, the lorica has a 

 dorsal crescentric excavation, forming two somewhat long 

 lateral points. The lorica is fiiiel}^ stippled. The head is a 

 truncated cone. There is a conspicuous eye. The trophi, as 

 far as observed, resemble those of C. luna. Length listh in., 

 breadth ^ioth in. Sp. ch. — Lorica fish-tailed, stippled, 

 crescentrically excavate in front, with somewhat long lateral 

 points. — J. S.] 



(xlvi) Monostylu quadridentata. Common. 



Family Colukid.e. 



(xlvii) Golurits hicuspidatus (?). Brighton. [The speci- 

 mens obtained closely resemble in most points the species 

 doubtfully written, but differ in possessing two eyes very 

 closely set, and two toes. Length ^iofh in., depth jloth in. 

 Length of foot -no^h in. — J. S.] 



(xlviii) Metopidia solidus. Brighton. 



(xlix) Metopidia ovalit; (n. sp.) Brighton. [The form 

 figured is beautifully transparent, and shows the internal 

 organs well. An egg-shaped lorica, broader posteriorly in its 

 dorsal aspect, possesses a slight excavation at either end, the 

 posterior one being at the summit of a slight projection 

 formed by the lorica curving outwards laterally. The 

 ventral plate has deep anterior and posterior openings of the 

 form of a half ellipse. Two eyes are set wide apart, each at the 

 base of a slight process set at each side of the corona. The 

 toes and foot much resemble those of M. solidus, as do the 

 general arrangement of the internal organs. Length o^o^h in., 

 breadth ifioth in.— J. S.J
