Amphilochella Schellenberg 



Amphilochella Schellenberg, 1926a. 



Type-species: A. simplicarpus Schellenberg, 1926a (monotypy). 



Mandibular molar absent; palp of maxilla 1 biarticulate ; maxilla 2 

 composed of one elongate plate; outer plates of maxillipeds not 

 excavate; palp article 1 shorter than article 2; gnathopod 2 small, 

 slender, scarcely subchelate; telson apparently entire. Species: 1,

Amphilochoides Sars 



Amphilochoides Sars, 1895. — Stebbing, 1906. 



Type-species: Amphilochus odontonyx Boeck, 1871 (original desig- 

 nation) . This species is figured by Sars erroneously under his Amphilo- 

 choides pusillus which becomes a synonym of A. odontonyx; Sars' 

 description and figures of A. odontonyx are proposed by him on p. 690 

 to have the name A. boeckii which Stebbing (1906) finds is a junior 

 synonym of Probolium serratipes Norman (1869a). 



Mandibular molar obsolete; palp of maxilla 1 biarticulate; lower lip 

 atypical for family, with tilted oval outer lobes astride distinct inner 

 lobes; maxilla 2 degraded but with two distinct subequal lobes; outer 

 plates of maxillipeds not excavate, palp article 1 subequal to article 2 ; 

 gnathopod 2 large, subchelate; telson entire. Species: 4, N.E.
