Introduction. 
Since the publication of the paper (in 1879 \) on the Devo- 
nian Entomides (the so-called u Cypridinen ”) of Germany, 
these little fossils have been frequently noticed by observers 
and writers, and their true generic position has been generally 
accepted. The lists of synonyms for the species here noticed 
will supply the more important references. 
A very extensive series of specimens has been obtained of 
three species by Mr. W. A. E. Ussher, F.G.S., in Devon- 
shire ; and from among them a selection has been made for 
illustration (see PI. XI. figs. 1-4). 
A very interesting species from the Eifel district has been 
described by Mr. J. M. Clarke, of Albany, New York, under 
the appropriate name of Entomis variostriata ; and he has 
kindly sent me some examples to examine and illustrate (see 
figs. 5-8 in the same Plate). 
Entomis serratostriata . — At page 516 of the ‘Versteiner- 
ungen rhein. Schicht.-Syst. Nassau,’ by G. and Fr. v. 
Sandberger, 1850-56, it is stated that Gypridina serrato- 
striata , Sand., had been met with at Petherwin, in Cornwall. 
In his Presidential Address for 1857 General Portlock 
expressed his doubts as to u Gypridina serratostriata ” 
having been found at South Petherwin, in Cornwall, or in 
the corresponding beds of the Pilton group in North Devon ; 
and stated that u Mr. Godwin- Austen informs me that he saw 
it, in company with Mr. F. Roemer §, in beds which he con- 
siders higher in the series ” (Quart. Journ. Geol. Soc. 
vol. xiii. p. lxxxix). 
In Dr. Bigsby’s ‘ Thesaurus Devonico-Carboniferus,’ 1878, 
* No. XXVIII. appeared in the Ann. & Mag. Nat. Hist, for October 
1889. 
t This Plate has been drawn with the aid of a grant from the 
Royal Society for the illustration of the fossil Ostracoda.

§ Dr. Ferd. Roemer tells me (in letter of September 30, 1889) that 
this was his late brother Fr. Adolph Roemer, of Clausthal ; also incor- 
rectly referred to as “ Ferd. Roemer/’ Ann. & Mag. Nat. Hist. ser. 4, 
vol. xi. (1873), p. 414.
