Paranthura, g. n., B. & W. 1. c. vol. ii. p. 1G3. Like Anthw'a, except in the 
structure of the pleon, which has the several segments distinctly articulated 
with each other, and carries the normal number of pleopoda. The authors 
think that this genus may possibly be synonymous with Olisica of Risso arid 
Hope. Paranthura costanea, B. & W. 1. c. vol. ii. p. 1G5 : this is undoubtedly 
the animal mistaken by Prof. Milne-Edwards for Anthura gracilis.

[^Cryptothiria.'] Dr. Buchholz, under the generic name of Ilemioniscus, has 
given (Zeitsclirift fiir Avissenschaftliche Zoologie, p. 303, 18GG) a full descrip- 
tion of the development of an animal that Avas long since named Liriopc by 
Rathke ; this name having previously boon used by Jjesson for a genus of 
the Mcdus(c,i\\ci authors of the ‘ British Sessile-eyed Crustacea ’ have adopted 
that given by Dana to a closely allied South-American species : — 
Hemioniscus, g. n. Eemina adulta corpore in partes duas distinctas 
diviso ; anterior pars caput et quatuor segmenta sequentia comprehendens 
cum posteriore continuo conjuncta, oculis simplicibus, quatuor antennis, ore 
euctorio et tribus paribus pedum uncigerorum triarticulatorum instructa, cum 
iisdem partibus larvae omnino congruens. Posterior corporis pars ex poste- 
rioribus thoracis [pereion] segmentis atque abdomine [pleon] formatum, an- 
teriore multo major sacciformis lobata, appendicum nulla vestigia praebens. 
Tractus intestinalis pars media A^alde dilatata cum appendicilius duabus coecis
