PLATE VIII. 



Ciliccea latrcillii, Leach. n.s., outline indicating natural size of specimen figured below in partially bent 

 position and in lateral view; Pl.V., ventral view of the pleon, omitting thepleopods; Pl.D., dorsal 

 view of the pleon with seventh segment of the person; a.s., upper antenna; a.i, a.i, both members 

 of the lower pair of antennae, to show the casual want of symmetry ; l.s., upper lip and epistome 

 from the upper (inner) side; Li, lower lip; m., m,, the two mandibles; mx. 1, mx. 2, mxp., the first 

 and second maxillae and the maxillipeds; gn. 1, prp. 5, the first gnathopod and the fifth peraeopod; 

 pip. 1, 2, 4, 5, the first, second and fifth pleopods, and part of the fourth; int., a small piece of the 

 integument from side-plate of seventh peraeon segment. 



The antennae, mouth organs, and limbs in detail are drawn to a uniform scale. The fragment of 

 the integument is more highly magnified. 



PLATE IX. 



A. Ciliccea whiteleggei, n. sp., . n.s., line indicating natural size of specimen figured above in partially 



bent position and in lateral view ; CD., dorsal view of head with first two segments of peraeon not 

 flattened out ; Pl.D., PI. V., dorsal and ventral views of pleon to the same scale as preceding figure ; 

 mx. 1, mxp., first maxilla and maxillipeds more highly magnified than the other figures, with one 

 exception; a.s., a.i, l.s., first and second antennae with epistome and upper lip; gn. 1, prp. 5, first 

 gnathopod and fifth peraeopod ; pip. 1, 2, 3, pip. 2, m.s., first, second and third pleopods, to the same 

 scale as the antennae and trunk limbs, but the separate male stilet of pip. 2 to the same scale as the 

 maxillipeds. 



B. Ciliccea whiteleggei, n. sp., ? . n.s., line indicating natural size of specimen figured above, much bent 



and in lateral view ; PI., pleon in dorsal view, with last segment of peraeon and parts of the two 

 preceding segments; a.s., a.i., first and second antennae; mx. 1, mxp., first maxilla and maxillipeds. 

 These are more highly magnified than the other details, and more highly than the corresponding 

 parts of the male; gn. 1, prp. 5, pip. 1, first gnathopod, fifth peraeopod, and first pleopod. 



C. Ciliccea sp., juv. n.s., line indicating natural size of specimen figured above, slightly bent, and in 



lateral view; mxp., maxillipeds magnified to the same scale as those in Plate IX., B; gn. 1, urp., 

 first gnathopod and uropod. 



PLATE X. 



A. Ciliccea beddardi, n. sp. $ . n.s., line indicating natural size of male specimen figured above in dorsal 



view; a.s., a.i., first and second antennae; l.s., upper lip with epistome; Li., lower lip; ?,, m,, 

 complete mandible on the right of the plate, and on the left the cutting edges and spine row of its 

 companion; mx. 1, mxp., first maxilla and maxillipeds; gn. 1, 2, pip. 1, 2, 3, 4, 5, the first and 

 second gnathopods and the five peraeopods in lateral view, connected together; pip. 1, 2, 5, the 

 first, second, and fifth pleopods ; urp., uropod. 



Of the details, the mouth parts are magnified on a higher scale than the other appendages. 



B. Ciliccea beddardi, n. sp. $ . n.s., line indicating natural size of female specimen figured above in dorsal 



view and not quite flat. Some of the details are from another female specimen ; juv., dorsal view 

 of a young one taken out of the specimen of which the mouth organs and pleon are figured ; 

 a.s., a.i., first and second antennae; m., Li., mx. 1, 2, mxp., mandible, lower lip, first and second 

 maxillae, and maxilliped, rather more highly magnified than the antennae and limbs; gn. I, prp. 1, 

 first gnathopod and first peraeopod ; PL, telsonic segment and uropods.
