Jones and Woodward—Fossil Phyllopoda. 533 
illustrated; and at p. 78, pl. ix. figs. 48-46, Macrocaris Gorbyi, 
n. gen. et sp. from the Keokuk group, at West Point, Indiana. Of 
this latter form, fig. 43 shows the interior of the carapace valves 
and four abdominal segments. Fig. 44 gives four and part of 
another abdominal segment, and the post-abdomen slightly broken 
at the end. Fig. 45 is eight abdominal segments and the post- 
abdomen. Fig. 46 is a tooth, found in the same rocks, that may 
possibly belong to the internal masticatory apparatus. 
-V. In the Canadian Record of Science, vol. v. No. 4, October, 
1892, pp. 205-208, Mr. J. F. Whiteaves gives a “Description of 
a new Genus and Species of Phyllocarid Crustacea from the Middle 
Cambrian of Mount Stephen.” The fossil is shown by a figure at 
page 206, and named Anomalocaris Canadensis, gen. et sp. nov. 
The diagram and description do not make it appear to us to bea 
Phyllocarid. 
VI. Mr. Robert Etheridge, jun., in the Records of the Geological 
Survey of New South Wales, vol. iii. part 1, 1892, pp. 5-8, pl. iv. 
describes and figures four specimens of the Hymenocaris Salter, 
M‘Coy, and states his belief that they belong to Lingulocaris; and, 
as there is a LZ. Salteriana, he thinks that they should be called 
L. Maccoyii. 
One or more specimens of this Australian species had been seen 
by Mr. J. W. Salter, and referred by him to Caryocaris with some 
doubt. We have adopted Mr. Salter’s conclusion, both in a former 
Report (for 1883) and in the Monogr. Brit. Paleeoz. Phyll., Pal. Soc. 
1892, p. 93. Comparing Mr. Htheridge’s figures with those of 
Caryocaris given by ourselves (op. cit. pl. xiv. figs. 11-15), we find 
that one of ours is as large as any of the former, and that the 
modified shape of the ends of the valves does not necessarily 
remove them from Caryocaris. 
VII. With respect to Aptychopsis cordiformis, sp. nov., and Pelto- 
caris anatina, Salter, mentioned at page 299 of the Report for 1892, 
Mr. J. KE. Marr informs us that the words “Coll. Marr” should not 
have been attached to the former in our Monogr. Pal. Phyll. 
part 2, 1892, p. 103, pl. 15, fig. 2, for it was collected long ago, 
being the only Paleozoic shield-shaped Phyllopod in the Cambridge 
Museum when Salter labelled it Peltocaris anatina, overlooking its 
real generic character, and perhaps regarding it as a distorted 
specimen. By this name the specimen has been referred to in lists 
of fossils as from “Wenlock,” and the real Peltocaris, which we 
have named P. anatina (Monogr. Pal. Phyll. p. 114, pl. 16. figs. 
4-9) is a “Llandovery” fossil. It seems to be expedient to give 
the old name anatina, instead of cordiformis, to the Aptychopsis 
(p. 103), as intimated by Mr. Marr in the Gronocican MaGazine 
for December, 1892, p. 535; and to distinguish the Peltocaris 
(p. 114), some specimens of which were collected by Mr. Marr, as 
P. Marri. 
VIII. We here append a table showing the geological distribution 
of the several Peltate Phyllopods described and figured in our 
Monograph and referred to at page 298 of the Report for 1892.
