"antero-lateral faces are pentao-onal (F, F') the postero-lateral rhomboidal (H, H'). The superior 

 " extremity of the proximal is cut into four facets; an anterior, hexagonal with concave lateral 

 "edges (D); a posterior, (juadrilateral meeting the last in a transverse ridge (CII) and two 

 "lateral rhombic faces which fit in between the anterior and posterior facets of the superior 

 "surface above and between the antero-lateral and postero-lateral below (G, G'). 



"The interior face presents an anterior quadrilateral facet (A) in the midst of which is 

 "a small aperture of the nectosac, surrounded by a five-toothed raised margin. Posteriorly the 

 "interior face slopes very oblicjuely upwards and backwards and presents a triangular space 

 "entirely occupied by the aperture of the hjdroecium (B)". 



Huxley found his single specimen in Torres Straits off the South-east coast of New-Guinea. 

 So we have sufficient reason to believe our specimen to be identical with it. As inferior necto- 

 phores, stem and appendages failed entirely we hope that other investigators may fill up this void. 



The name Abyla alata Hkl. is to our opinion not a good one as the eudoxids ol 

 Abyla trigona are called thus and we do not know after all if the eudoxids of Abyla trigona 

 and Abyla Haeckeli are similar. 



We would have liked to call these specimens Abyla Huxleyi, as Huxley after all found 

 these for the first time. But this name has already been used by A. Agassiz and A. G. M.\yer 

 1902 (see Abyla pentagoiia p. 25).

The only investigators who have found this interesting Abyla Leuckarti are Huxley and 

 A. Agassiz and A. G. AL\yi:r. 



Huxley's specimens had a length of f\, mm., a breadth of 4 mm., A. Agassiz and 

 A. G. Mayer give the very con.siderable dimension of 22 mm. in length. Neither of them give 

 a distinct description of the shape of the facets.
