ARTHROPOD FAUNA OJP THE WEST INDIES. 523' 



I have not seen any specimens of Peripatus from Trinidad 

 •with which to compare these Dominican individuals. Two of them^ 

 however, were sent by Prof. Bell to Prof. Sedgwick, who stated 

 (in MS.) that they were more nearly related to trinidadensis 

 than to any other Neotropical species. Certainly the third, and 

 largest, specimen, which was, I believe, not seen by Prof. 

 Sedgwict, possesses at least as many as ten minor teeth on the 

 inner blade of the jaw of the left side ; so in this character, as 

 well as in the number of its legs and shape of its papillae, it 

 agrees with Prof. Sedgwick's trinidadensis. There can be very 

 little doubt, I think, as to the distinctness of this form from 

 juliformis ; but I am strongly disposed to thiuk (1) that it will 

 prove to be the same as the Demeraran species Imthurni t, 

 Sclater ( = demeraranus, Sedgw.) , and (2) that both names will have 

 to be added to the synonyms of Edwardsii of Blanchard. Im- 

 thurni and trinidadensis apparently agree in the conical J form 

 of their papillae as well as in the number of legs in the female. 

 The males, however, are unknown.

" Colour of dorsal surface red-brown, the middle of the back 

 being somewhat darker, and paling off towards the sides. Head 

 and tentacles black, and marked off from the body on the dorsal 

 side by a bright yellow band, which often shows a small inter- 

 ruption in the middle line. Ventral surface has a dark flesh- 

 colour." 



Number of pairs of legs 41-42. 



Length of female 150 mm., width 8 mm. ; length of male 100 mm. 



Locality. Trinidad, 



This appears to be a well-marked species on account of its 

 large number of legs and the presence of the yellow band behind 

 the head. 



t Described briefly by Mr. W. L. Sclater on p. 133 of the P. Z. S. for 1887, 

 and subsequently named in the ' Quart. Journ. Micr. Sci.' xxviii. p. 344 ; on 

 p. 476 of the latter volume Prof. Sedgwick proposed the name demeraranus a* 

 a substitute for Imthurni. 



X On pp. 475-476 of the monograph Prof. Sedgwick points out that in deme- 

 rarcmus the principal papilliB have conical bases, and thus differ from the same 

 structures in his Edwardsii, which are cylindrical but in his brief diagnosis of 

 demeraranus on p. 476, and again on p. 488, he says " cylindrical lirimary 

 fapillce!^
