Hymenicus pubescens, Dana, U.S. Explor. Exped. xiii, Crust. part 1, 
p. 388, pl. xxiv, fig. 11, (1852). 
Carapace pubescent, very nearly orbiculate or hardly ovato-orbiculate, 
arcuate behind, beak small, quite simple, rounded, margin pubescent, 
whole margin of carapace entire, unarmed. Abdomen of male narrow, 
linear, sub-triangular, penult. joint and two preceding nearly equal, 
slightly narrowing posteriorly, last segment sub-triangular, a little 
oblong, obtuse. Feet short, pubescent, the anterior of moderate size, 
the others slender, but less so than in H. varius. Length 14 to 2

New Zealand; Bay of Islands (Dana); Auckland (Heller). 
Distinguished from the Hymenicus depressus, by the absence of 
the small tooth, outside the eyes. Both this and the foregoing species 
are unknown to me. From their small size they may be young forms.

Hymenoscma depressum, Jacquinot and Lucas, Voy. Pole Sud 
Zool. ii, p. 62, pl. v, fig. 84, (1855).

legs rather swollen, very short, the fingers elongated, narrow-ciliated 
on the inner margins, the ambulatory legs very much elongated, 
slender, smooth. Colour reddish-yellow. Length about ? in. ; breadth 
about Zin. (J. & L.).

The carapace is represented as nearly circular, the front very 
narrow, not longer than the eyes, and of equal width throughout. 
There is apparently a small tooth outside the eyes. Third joint of 
the external maxillipeds much the largest. 1 have not seen specimens 
of this species.
