Type-species: M. fuegiensis Schellenberg, 1931 (monotypy). 



Head i)oorly rostrate, not massive; eyes lateral; antennae short, 

 subequal in length, peduncle of antenna 1 slightly longer than head,

 cessory fiagellum absent; upper lip not incised; [epistome unknown]; 

 mandible lacking palp, with large triturative molar and toothed incisor; 

 lower lip with inner lobes separate, outer lobes with mandibular 

 extensions ; inner plate of maxilla 1 with one terminal seta, outer plate 

 with 10 spines, palp 4-articulate, article 4 unguiform; coxae long as in 

 normal gammaridean, coxa 4 not excavate posteriorly; gnathopods 

 1-2 weakly subchelate, of medium size, similar to each other, articles 

 5-6 subequal in length; pereopods generally like those of Oediceros 

 saginatus (see Sars, 1895, pi. 102), thus fossorial, pereopods 1-4 with 

 vestigial dactyls; uropods 1-2 normal, aj^ices of rami spinose; uropod 

 3 reduced to a small simple triangular peduncle; telson nearly circular, 

 entire. Affinities with Dogielinotidae but epistome unknown. Species:

Sphaerophthalmus Spandl 



Sphaerophthalmus Spandl, 1923; 1924. 



Type-species: 5*. grobbeni Spandl, 1923; 1924 (monotypy).

 antenna 2 ''3-articulate"; maxillipeds apparently with medium sized 

 inner lobes, enormous subclavate outer lobes nearly exceeding the 

 moniliform 4- (?3-) articulate palp, the terminal article of which lacks 

 distinction; other mouthparts not described; gnathoi)od 1 stout, like 

 that of stegocephalids, gnathopod 2 more slender, elongate, article 6 

 expanded and bearing transverse i)alm as in gnathopod 1 ; pereopods 

 of medium length, second articles of j)ereopods 3-5 expanded; uropods 

 1-2 normal, rami interequal, ai)ically spinose, uropod 3 with short 

 peduncle and leaf-like rami; telson elongate, cleft nearly to base.
