G. M. Tuomson.—On New Zealand Pycnogonida, 245 
All the joints are remarkably smooth, and destitute both of hairs and 
spines. The 2nd tarsal joint is strongly spined along its inner margin, 
while its outer margin protrudes beyond the articulation of the large claw 
and its auxiliary claws into a tubercular prolongation, which is beset with 
several minute spines. 
The genital openings on the 2nd joints of all the legs are very small and 
inconspicuous. 
The integument is everywhere covered with minute rounded tubercles. 
Hab. A single specimen of this apparently very distinct species was 
forwarded by Mr. C. Chilton, who obtained it by the dredge in Lyttelton 
Harbour. 
Genus II. Oorhynehus, Hoek. 
Proboscis ovate, inserted ventrally on the cephalothorax at a consider- 
able distance from the front margin. Mandibles rudimentary ; palpi 
9-jointed. Ovigerous legs 10-jointed ; the four last joints not furnished 
with one or more rows of denticulate spines. 
5. Oorhynchus aucklandie, Hoek. (See p. 242.) 
Fam. III. PALLENIDA. 
Mandibles strongly developed, cheliform ; palpi rudimentary or quite 
wanting. Ovigerous legs present in both sexes, and furnished with 
denticulate spines (Pallene), or in both sexes and furnished with simple 
spines (some species of Phoxichilidium), or present in the males only (other 
species of Phowichilidium). 
(Nore.—In Dr. Dohrn's monograph, a somewhat different classification 
of these genera is given :— 
Phoxichilidium is placed in the family Phoxichilide, and is characterized 
as possessing mandibles furnished with nipping claws, palpi wanting or 
only present as a rudiment in the male, ovigerous legs 5-T-jointed, only 
present in the males, and furnished with simple spines. 
Pallene is placed in the family Nymphonide, and is characterized as 
possessing mandibles furnished with nipping claws, palpi wanting or only 
present as a rudiment in the male: ovigerous legs present in both sexes, 
10-11-jointed, furnished with leaf-like or finely toothed spines on their 
terminal joints. From this genus again he separates Neopallene as 
follows :— 
a. Sexual organs and their genital openings present in the 
2nd, 3rd, and 4th pairs of legs (Extremität V.-VIL), 
wanting in the 1st pair (Extremität IV.); palpi 
rudimentary in the male  ... T na ae 
b. Sexual organs and their genital openings present in 
all the legs; palpi wanting in the male hi 
Neopallene. 
Pallene.
