Family. Latreutidae. 



Genus. Parhippobjte nov. 



The absence of a cutting edge (psalistonia) from the mandible of the species on 

 v,'hich this new genus is founded obliges me to place it in Ortmann's new family, 

 Latreutidae. [Bronn's " Thierreich," Crust. Ii. p. 1130 (1898).] It is, however, so closely 

 allied to Merhippolyte Bate that it might almost equally well be placed like the latter 

 group as a subgenus of Spirontocaris Bate (non Hippolyte Leach, restrict.). In any case, 

 the difference between the Latreutidae and Hippolytidae will not, I think, be ultimately 

 found to be of more than subfamily value. 



Characters of Parhippolyte n. gen. 



1. Rostrum moderate, dentate. 



2. Supraorbital spine wanting, antennal and postorbital spines present. 



3. Flagella of first antenna long. 



4. Mandible without cutting edge, with three-jointed palp. 

 .5. Third maxilliped with exopodite. 



6. Second wrist multiarticulate (about 30 joints). 



7. Branchial formula as in Merhippolyte but no pleurobranch on third maxilliped. 



8. Sixth abdominal segment with the hinder angle provided with a small spine, 

 but not articulated.

Diagnosis : — " A Parhippolyte with the rostrum, bearing three or four teeth above 

 and five below; with antennal and postorbital spines present, the pterygostoniial 

 angle of the carapace rounded and the anterior two-thirds dorsally carinated ; the 

 antennular stalk half the length of the antennal scale, its first joint almost equal to 

 the second and third together, the stylocerite equal to the first joint, broad, acute, the 

 flagella subequal ; the scale of the second antenna long, broad at the base, narrowing 

 rapidly, with the spine barelj' projecting beyond the free end, flagellum about equal to 

 the antennular flagella ; third maxilliped outreaching the antennal scale by the last two- 

 thirds of its last joint, which is obliquely truncated at the end ; first leg not reaching 

 the end of the antennal scale, hand equal to wrist, fingers shorter than palm, not 

 dentate, with a small black claw at the tip ; second leg outreaching by the WTist the 

 antennal scale, \vrist about 30-jointed, first and last joints subequal, about twice the 

 length of any of the others ; remaining legs long, the last slightly the longest, owing 

 to increased length of the propodite, meropodite with spines underneath ; endopodite of 

 iiropod as long as telson, exopodite longer ; telson ending in a median spine and 

 bearing at the end four lateral spines and on the dorsal surface four jjairs of spines." 



Length 110 mm. 



Ten specimens, ? all female. Three with eggs. From Uvea, Loyalty Islands.
