pi. 34, fig. 1), but has a more elongate pleon aiid a less produced and 

 blunter median process on the head. The epipod of the maxilliped 

 and the 2nd pleopod are very much alike in the two species. 



EURYCOPE FUSIFORMIS 11. sp. 



(Plate XVII. Fig. 19.) 



Female. Body widest in the middle, tapering towards both ends, 

 smooth, glabrous. Head strongly emarginate in front, lateral portions 

 not developed. Peraeon segment 1 wider than head, segments 1-4 

 increasing gradually in width, antero-lateral angles of 1 and 2 quadrate, 

 of 3 and 4 shortly acute ; segment 5 widest of all, longer laterally 

 than dorsally, autero-lateral angles rounded-quadrate, posterior margin 

 concave ; segment 6 of same length laterally as dorsally, posterior 

 margin concave ; segment 7 longer dorsally than laterally, posterior 

 margin straight ; segments 5-7 closely united, with nearly straight 

 and even lateral margins, narrowing gradually posteriorly. Trans- 

 verse ridges not developed. Side-plates distinct only on segments 3 

 and 4. Pleon at base as broad as peraeon segment 7, almost an 

 equilateral triangle in shape, lateral margins slightly convex, apex 

 subacute. 



Antenna 1, 1st joint stout, 2nd short and much narrower, 3rd very 

 slender, flagellum at least 5-jointed, 1st very short. 



Antenna 2, except the basal joints, lost. 



Maudibular palp with 3rd joint falciform. 



Epipod of maxilliped broad, the inner margin and the proximal 

 portion of outer margin subparallel, the distal portion of outer 

 margin bevelled off straight or very slightly concave to the subacute 

 apex. 



All the peraeopods lost. 



Operculum with a broad strong keel extending to apex. 



Length: 3'5 mm. ; breadth: I'D mm. 



Colour: In spirit pinkish-white. 



Locality: Cape Point N. 89 E., distant 36 miles. 700 fathoms.

This species is in general appearance like Ili/arachna plunlcetti 

 Tattersall (I.e. p. 28, pi. 7), but differs in having the anterior margin 

 of 7th peraeon segment strongly convex and the pleon shorter relatively 

 to its length two features which bring it very close to I. abyssoram 

 Eich. (Bull. Mus. d'Hist, Nat, Paris, 1911, no. 7, p. 533). Both 

 species are without lateral developments of the head, but the latter 

 species has no palp to the mandible and a distinctly biramous uropod.
