CRUSTACEA. 
^33 
Prof. Lilljeborj^ likewiso statoa that tho Anonyx ampulla " introduced under 
this name in the ^ British Sessile-eyed Crustacea ’ is a totally different one.” 
Of course all observers are liable to error, particularly in comparing figures 
and descriptions -with specimens ; but wo think that in this instance the 
error does not exist on the part of the authors of the ^ Sessile-eyed Crustacea.’ 
On comparison of the figure given in the ^ British Sessile-eyed Crustacea ’ 
with Kroyer’s in Voy. Scand. pi. xiii. fig. 2, to which Prof. Lilljeborg does 
not refer, we think the resemblance will be found to be too close to have 
justified the authors in placing it in any other position than that which they 
have done. — A. longipes (Sp. B.), Lilljeborg, 1. c. p. 23, from Haugesund, &c. 
The author considers A. ampulla of the ^British Sessile-eyed Crustacea’ the 
male of this species. — A. gulosus (Kroyer), Lilljeborg, L c. p. 24, from Bohusliin 
to Finmark. This species the author states to be identical with A. holholli of 
the ‘ British Sessile-eyed Crustacea,’ as well as with A. norvegicus of Lilljeborg 
and Bruzelius. — A. hruzelii (Boeck), Lilljeborg, h c. p. 28, from Norway; A. 
nanus (Kroyer), Lilljeborg, 1. c. p. 28, from the Kattegat and Farsund ; A. pin^ 
guts (Boeck), Lilljeborg, 1. c. p. 29 ; yf . serratus (Boeck), Lilljeborg, 1. c. p. 29, 
tab. iv. fig. 60, from Grip near Christianssund. Prof. Lilljeborg considers that 
A. edwardsii (Sp. B.) belongs to this species. — A. edwardsii (Kroyer), Lilljeborg, 
1. c. p. 30. This species is unknown to the author. — A. lUoralis (Kroyer), Lill- 
jeborg, 1. c. p. 30, from Warangarfjord, extreme north of Norway ; A. TiolhoUn 
(Kroyer), Lilljeborg, l.c. p. 31, from Bohuslan to Finmark, also Norman, Trans. 
North. & Burh. Nat. Hist. Soc. vol. i. p. 12, off the coast of Durham. Prof. 
Lilljeborg considers A. denticulatus (Sp. B.) the male of this species. — A. 
ohtusifrons (Boeck), Lilljeborg, l.c. p. 32, Norway; A. tumidus (Kroy.), 
Lilljeborg. U c. p. 32, tab. iv. fig. 6, taken in the branchial sac of an Asci-* 
dian in the Kattegat.

paris palpo, et palpus maxillipedum ungue carentes, et hae partes oris con- 
junctim acumen productum praebent. Pedes trunci primi paris [anterior pair 
of gnathopoda] robusti, manu prehensili. Pedes secundi paris [second pair 
of gnathopoda] graciles, ungue carentes. 
A. ohcsum (Sp. B.), Lilljeborg, 1. c. p. 34, tab. v. figs. 63-66, from Molde, 
Farsund, and Bahusia. Prof. Lilljeborg considers Anonyx ohcsus suflicientlj’^ 
structurally distinct from the other species of Anonyx to require a separate 
genus ; in this conclusion we cannot coincide, as all the distinguishing con- 
ditions are changes in degree only.
