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. Oorhynelms, 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 auchlandim, Hoek. (See p. 242.) 

 Farn. III. PALLENIDiE. 



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 Phoxichilidium). 



(Note. — In Dr. Dohrn's monograph, a somewhat different classification 

 of these genera is given : — 



Phoxichilidkim is placed in the family PhoxichilidaB, and is characterized 

 as possessing mandibles furnished with nipping claws, palpi wanting or 

 only present as a rudiment in the male, ovigerous legs 5-7-jointed, only 

 present in the males, and furnished with simple spines. 



Pallene is placed in the family Nymphonidse, 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 (Extremitat V.-VIL), 

 wanting in the 1st pair (Extremitat IV.) ; palpi 

 rudimentary in the male ... ... ... r .. Neopallene. 



b. Sexual organs and their genital openings present in 



all the legs ; palpi wanting in the male Pallene.
