MONOGRAPH OF THE GENUS PERIPATUS. 479 



Peripatus found atCayenne, when better known, will turn out 

 to be a distinct species. 



3. Wiegmann (No. 4) obtained a specimen of Peripatus 

 from near the Valentia Lake in Columbia, with thirty pairs 

 of legs. It is quite impossible to say whether this is a distinct 

 species or not. It possesses, according to Wiegmann's descrip- 

 tion, four spinous pads on its legs and a generative opening 

 between the legs of the penultimate pair. 



4. C. Mority (No. 5) obtained a large number of Peripatus 

 from the Island of St. Thomas. He gives no details. 



There is a specimen in the British Museum from St. Thomas. 

 It has twenty-eight pairs of ambulatory legs, and is of a 

 yellowish-brown colour, but is unfortunately too ill-preserved 

 for determining any specific characters. 



5. Peters (No. 24) mentions specimens from Utuado, Porto 

 Rico, and gives the following particulars. 



Specimens 21 mm. in length had 27 pairs of legs. 

 „ 33 mm. „ „ 30 „ 



38 mm. „ „ 31 „ 

 „ 42-48 mm. „ „ 32 „ 



6. Blanchard (No. 8) has described a Peripatus found in 

 Chili by M. Claude Gay, with nineteen pairs of legs. His 

 description is as follows : — " Le corps est long de 30 a 32 

 mill., et large de 5 a 6, legerement attenue aux deux extremites, 

 mais surtout vers la partie posterieure. Sa couleur est noire, 

 un peu variee irregulierement de taches roussatres. La tete 

 est presque carree avec les antennes amincies vers le bout, 

 presentant des annulations tres serrees. L'orifice buccal est 

 ovalaire. Les pattes sont au nombre de dix-neuf paires, ciliees 

 de poils raides comme de petites pointes, et terminees par des 

 crochets." 



There is obviously nothing in this description which enables 

 us to say whether the three specimens at the author's disposal 

 possessed the characters of the Neotropical species or not. 

 It is extremely probable, considering the remoteness of the 

 locality, that this is a distinct species ; but unfortunatelv
