NEOTROPICAL SPECIES. 201 



mentary papillae constricted, and arranged on the dorsal 

 surface in regular rows. Length about 48 mm. ; body cylin- 

 drical in shape with a diameter of about 4 mm. The legs are 

 ■without tubercles. 



7. Finally there is a specimen labelled " Peripatus Santarem, 

 Wickham, purchased of W. H. J. Carter." It has thirty-one 

 pairs of ambulatory legs, and presents, so far as its external 

 features are concerned, the Neotropical characters. The papillae 

 are conical, and the legs are without tubercles. 



Professor Steenstrup was kind enough to send me for exam- 

 ination the specimens in his museum. I desire to take this 

 opportunity of thanking him for his courtesy and kindness in 

 the matter. The Copenhagen specimens were in four bottles : 



(1) Label " Peripatus Edwardsii, Bl., Vestindien, Kroyer." 

 This was a fine, well-preserved specimen, with thirty-one pairs 

 of ambulatory legs, and a brown colour. The dorsal surface was 

 darker than the ventral. The dorsal papillae were remarkably 

 large (fig. 14) and constricted, as were also the ventral, but less 

 markedly. The generative opening was between the legs of 

 the penultimate pair, and the spinous pads of the legs were 

 four in number. 



(2) Label " Peripatus Edwardsii, Blanch., St. Croix, Kroyer." 

 This specimen, which in general appearance resembled the first, 

 but was smaller, possessed twenty seven pairs of ambulatory 

 legs. Spinous pads and generative opening as in (1). 



(3) Label "Pen^a^MS Fe*<mc?ieM, Hombek (?)." With thirty- 

 two pairs of ambulatory legs. 



(4) The specimen in the fourth bottle was not sufficiently 

 well preserved for observation. 



It is unfortunate that the exact localities of the above were 

 not recorded. They are obviously all Neotropical species, but 

 to which of these they belong cannot be at present settled. 



Four specimens of Peripatus, of which one had thirty-one 

 pairs of legs, are reported from Demerara (Hoorubea Creek, 

 twenty miles from Georgetown, on east side of Demerara river), 

 by Mr. J. J. Quelch (No. 36). No details are given.
