Carpenter — Torres Straits Pycnogonida. 553 



Family.— PALLENID^. 

 Genus. — Parapallene, gen. nov. 



I suggest this genus to receive Pallene australiensis, Hoek, and 

 a new species, both of which were collected by Professor Haddon. 

 Sars (6) points out that the genus Pallene in its present restricted 

 sense cannot be made to include Hoek's three " Challenger" species, 

 each of which will probablj'' become the type of a distinct genus. 

 Parapallene, of which Pallene australiensis, Hoek, may be taken as 

 the type, is distinguished by the following characters : — 



Body slender and elongated ; posterior trunk segments sepa- 

 rate ; proboscis short and blunt, swollen at anterior end ; lateral 

 processes well separated ; false legs, with spines slightly or not 

 denticulate ; tarsi of legs without auxiliary claws. 



The genus seems to come nearest to Pallene, from which the 

 absence of auxiliary claws on the walking-legs and the indepen- 

 dence of the two last trunk-segments from each other distinguish it. 

 The body is much more slender than in Pseiidopallene and Cordy' 

 lochele. The simple nature of the spines on the false legs also 

 distinguish it from other genera of the Pallenidse. 



Parapallene australiensis (Hoek). 



Pallene australiensis, Hoek, " Challenger," Zoology iii., p. 76, 

 pi. xi., ff. 1-7. 



A single female was obtained by Professor Haddon. 



Only three specimens were dredged by the "Challenger," and I 

 am not aware that the species has been recorded since. The two 

 stations where the " Challenger" specimens were found are off the 

 south coast of Australia — one in Bass's Straits, the other off 

 Twofold Bay, and the depths were 40 and 120 fathoms respec- 

 tively. The discovery of the species between reefs in Torres 

 Straits, at the northern extremity of the Australian continent, 

 proves, therefore, that it has a considerable geographical and 

 bathymetric range.
