position similar to that of the same structure in Peripatus 

 novae-zealandice. The uterus was empty. 



In the male the genital organs were normal, and the 

 unpaired portion of the vas deferens was long, and apparently 

 of a similar structure to that of the New Zealand species. 



The specimens were not sufficiently well preserved for an 

 examination for the accessory glands. 



PERIPATUS FROM THE NEOTROPICAL REGION. 



Peripatus is found all over the northern part of the Neo- 

 tropical region. It is reported from Chili, Columbia, Cayenne, 

 Venezuela, Nicaragua, and from many of the West Indian 

 Islands, viz. Jamaica, Cuba, Trinidad, St. Thomas. I unfor- 

 tunately have only been able to make a complete study of the 

 species from Venezuela and of that from Demerara ; of some 

 of the remainder I have only seen single specimens, or specimens 

 the preservation of which was not sufficiently good to allow of 

 the determination of specific characters. A partial exception 

 must be made in favour of the small species from Trinidad, of 

 which Dr. J. v. Kennel has been good enough to send me two 

 specimens ; but these were, unfortunately, somewhat contracted 

 and not sufficient in number to enable me to generalise as to 

 specific characters. I trust, however, that the careful description 

 of the Venezuela species, the specimens of which were collected 

 by Professor Ernst at Caracas, and given to Professor Balfour, 

 willform a groundwork on which future collectors of Peripatus 

 from this region will be able to work. 



Although I have failed in determining the relations between 

 the various specimens of Peripatus which have been found in 

 the Neotropical region, still I have seen enough to be able to 

 establish a certain number of characters which distinguish a 

 great number — and probably all — of the neotropical Peripatus 

 from those found in other regions. Those characters are stated, 

 in the following definition :
