27. Thysanopoda? amblyops n. sp. 



Body somewhat elongated, subcylindrical. Carapax without any 

 lateral denticle, anterior part very slightly keeled above; rcstrum 

 short, triangular. flatteued. Postabdominal segments smooth above, 

 epimera small and evenly roimded. Last segment longer tban the 

 preceeding; præanal spine obsolete. Eyes scarcely expanded at 

 the end, cornea very small, with the optical parts imperfectly 

 developed. Antennular peduncle unnsually thick and massive, 

 without any dorsal lappets. Antennal scale reaching the tip of 

 the antennular pedimcle, oblonge, apex roimded, the denticle on 

 the outer edge distinct. Legs (only the anterior pair preserved) 

 unnsually short and robust, with much flattened joints. Telson not 

 much elongated, evenly tapering, apex acuminate; subapical spines 

 smooth aud elongated. Uropods shorter than the telson, outer 

 lamella of somewhat unusual shape, rather broad, with a strong 

 spine at the outer margin, apex very obliquely truncated; inner

Hab. South Atlantic, offTristan d'Acunha, 1000 fms. A single 

 imperfect specimen. 



Remarks. It may be. that this fonn more properly ought to 

 be regarded as the type of a new genus allied to Thysanopoda ; 

 but as the solitary specimen does not allow any closer anatomical 

 investigation, I prefer to describe it preliminarily as a species of 

 that genus. 



Gen. 3. Nyctiphanes 1 ri. 



Goieric characters. General form of body almost as in Eiiphau- 

 sia. Flagella of both pairs of anteunæ greatly elongated. Anten-
