Tegastes longimanus (Glaus). 



(Suppl. PI. 9, fig. 3). 

 Amymone longitnana, Claus, I.e. p. 115, PI. 20, figs. 13 & 14. 



Specific Characters. Female. Cephalic segment without any chitinous 

 stripe across the back, postero-lateral corners rather produced, though somewhat 

 less acute than in the 2 preceding species ; rostral prominence well marked. Ge- 

 nital segment slightly protuberant below and produced into 2 successive recurved 

 blunt dentiform projections. Distal part of urosome scarcely prominent. Anterior 

 antennae unusually short and apparently composed only of 7 articulations. Post- 

 erior maxillipeds of a very characteristic appearance, being much elongated, with 

 the basal part composed of 2 slender joints forming together an elbow-shaped 

 bend, hand comparatively short, but much dilated at the base, almost triangular in 

 shape, palmar edge concave behind, and forming in front a strong arcuate bulge 

 armed with 4 slender spines, dactylus rather strong and curved. Legs apparently 

 of normal structure. 



Colour not yet ascertained. 



Length of adult female 0.27 mm. 



Remarks. This is unquestionally the species originally recorded by Claus 

 under the name of Amymone longimana. It is specifically distinct from the form 

 described on page 70 of the present work as Claus's species, and I propose to 

 name that species Tegastes Clansi. The very peculiar shape of the posterior max- 

 illipeds will at once make the present species recognisable from any of the others. 



Occurrence. Of this form also only a single female specimen has come 

 to my notice. It was found in a sample taken at Kopervik, SW coast of Nor- 

 way, from a depth of about 15 fathoms. 



Distribution. Heligoland (Claus), ? British Isles (Brady).

For Idya, Philippi, 

 read: Idycea, Philippi. 



Remarks. The above slight change oif the Philippian name was proposed 

 by the present author last year (Report on the Crustacea of the 2nd Fram Ex- 

 pedition), in order to keep it apart from Idya Freminville (a genus of Acalephse).
