DISTRIBUTION AND CLASSIFICATION OF ONYCHOPHORA. 391 
18. Crural glands in the male in the two pairs of legs pre- 
ceding the genital opening; there are two pairs in each leg ; 
they open into the groove of the coxal organ, and are without 
papillee. 
19. The accessory glands of the male open between the 
legs of the last pair by a common opening. 
This is an exceedingly interesting group of species, for it 
shows, together with several peculiar features, viz, 3 + 4, 5, 
9a, an important character only found elsewhere in Austro- 
Peripatus, viz. 11; and in the form of its jaws, in the 
number of its spinous pads, the position of the genital open- 
ing, the presence of a receptacula ovorum, it approximates 
markedly to Neo-Peripatus. But it is removed from Neo- 
Peripatus by its exogenous ovary, as well as by its large 
ova. It appears to hold 14 and 15 in common with Neo-, 
Congo-, and Austro-Peripatus. On the whole this group of 
Species 18 as distinct as any, and is especially interesting as 
showing a mingling of characters which are found elsewhere 
only in Neo-Peripatus or in Austro-Peripatus. On the 
other hand it is worthy of remark that it shows nothing in 
exclusive community with Capo-Peripatus. 
MELANO-PERIPATUS.—In 1897 Peripatus was discovered 
by Dr. A. Willey in New Britain. He wrote a full descrip- 
tion of its anatomy and development, and named it 
P.nove-britannie. Its characters are as follows: 
1. The number of legs (22—24 pairs) is variable in the 
species. 
2. The outer jaw is without a minor tooth, and the inner 
~ jaw has no diastema or saw. 
3. Legs with three spinous pads. 
4. Nephridial opening of legs 4 and 5 are on the proximal 
pad. . 
5. Feet with three distal papilla, one of which is anterior, 
one dorsal sometimes inclined to the anterior side, and one 
posterior (Fig. 9).
