Remarks. As to the mesenteries, the species shows an organ- 
ization spmewhat different from the previously described Peachia 
species. It is possible that the species is an anormal Individuum 
(compare Carl gren 1921, p. 104) and never develops the missing 
mesenteries of the second order. It is, however, more likely that 
the specimen is not full-grown, though the reproductive organs are 
rather well developed. 
Judging from the description of Peachia hilli (Wilsmore 1911, 
p. 39) dredged in Broken Bay, New South Wales, this species 
is not identical with P. neozelanica. I have not identified our 
species with P. carnea Hutt. (Hutton 1879, p. 275) as it is very 
doubtful if this species really is a Peachia. Hutton’s short de¬ 
scription of P. carnea is as follows: “Column flesh colour, semi- 
transparent with pale longitudinal lines, contracted below the mouth 
and again about one third from the posterior end but the form is 
variable, anus (!) large and conspicuous. Disc pale flesh colour, 
rayed with brown. Mouth rayed surrounded by a brown-banded 
ring, on one side a number of small papillae. Tentacles 12, rather 
longer than the diameter of the disC, simple pale flesh colour with 
about five brown, often chevroned, bands on the upper surface. 
Length about IV 4 inch. A single specimen. Ocean Beach, Dunedin.“ 
Fam. Condylanthidae. 
I accept Stephenson’s proposition to form a family Condy¬ 
lanthidae for the genus Condylanthus. According to this author, 
(1922, p. 262) Charisea should be a synonym of Condylanthus. To 
my mind it is not so, as the description and especially the figures 
of Torrey (Proc. Wash. Acad. Sc. 4. 1902, p. 388) indicate that 
there is no real pedal disc in this genus. Therefore, and also on 
account of other structural characters, I have (1921, p. 92) sug- 
gested that Acthelmis and Charisea are synonyms. In Condylanthus 
the lower part of the column is much broader and provided with 
more numerous mesenteries than the upper part, while in Charisea 
with its vermiform body the number of tentacles and mesenteries 
agree. On account of the excluding of Charisea from the Condy¬ 
lanthidae and of the structure of the genus Condylanthus (compare 
below) the diagnosis of the family must be altered as follows:
