Tlie Anatomy of Oinstliopatus cinctipes. 107 



All the principal types of colouration described on p. 97 occur 

 amongst these specimens, viz : — 



(1) Beddish speciviens. — The prevailing colour of the dorsal and 

 lateral surfaces of the body (including most of the papillae) is a light 

 brick-red (terra-cotta), with a small and varying amount of dark 

 green scattered about between the papillge, especially towards the 

 posterior part of the body. A varying number of small papillae are 

 also dark green and these are mostly distributed about midway 

 between the medio-dorsal line and the legs in the region corre- 

 sponding to the upper dark lateral stripes in P. balfouri, &c., giving 

 rise here to a similar but rather indistinct stripe. The lateral band 

 just above the bases of the legs is pure light brick-red, without any 

 green whatever. On the dorsal surface of the legs transverse bands 

 of large brick-red papillge alternate with bands of smaller dark green 

 papillge. 



(2) Dark greenish specimens loitli red sides. — In these most of 

 the smaller papillae on the upper and on part of the lateral surfaces 

 and a large amount of the surface between the papillae are dark 

 green, excepting quite anteriorly, so that the back appears dark 

 greenish with a reddish tinge owing to the presence of numerous 

 large brick-red papillae. The lateral bands are light brick-red with a 

 small amount of dark green, and the legs possess alternating bands 

 of dark green and brick-red papillae on their outer surfaces. 



(3) Dark green specimens, like the original types. — Prevailing 

 colour dark green, the reddish pigment of the upper and lateral 

 surfaces being confined to a smaller number of large papillae (resem- 

 bling P. balfouri, leonina, and clavigera in this respect) ; these 

 papillae occur also in the paler green lateral band above the bases of 

 the legs on each side, while on the outer surfaces of the legs they 

 may be fairly plentiful or almost entirely absent and do not form the 

 distinct alternating bands found in the reddish specimens.

 (J. L. Drege). 



(c) Six ? , two 3- and several newly-born young, all living, besides 

 several dead specimens, from Eichmond, Natal,* collected by Mr. 



* After this paper had gone to the printers, a paper by Bouvier came to hand, 

 entitled " Quelques observationes sur les Onychophores (Peripatus) de la 

 collection du Musee Britanique" (Q.J.M.S. (2) sliii. pt. 2, pp. 367-373, 1900) 

 dealing, amongst others, with O. cinctipes, P. moseleyi and P. sedgwicki. I 

 shall only mention here that Bouvier records specimens of 0. cinctipes from 

 Durban, Natal, in which he observed the cruciform sexual opening and the large 

 coxal organs (on the 6th to 16th pairs of legs inclusive). On this account, as
