NOTES ON PHYLLOPOD CRUSTACEA 
A. S. PKARSE, HONORARY CURATOR OP CRUSTACEA, UNIVERSITY OP MICHIGAN 
MUSEUM. 
A small collection of phyllopods in the collection of the University 
of Michigan Museum was turned over to the writer for examination. 
The following notes include descriptions of three species that appear to 
be new and some points of interest concerning six others. 
Thanks are due Dr. G. S. Dodds and Professor C. W. Hargitt, who 
sent specimens from Colorado and New York respectively. 
Eubranchipus dadayi sp. nov. 
Male: First antennae slender, longer than eyestalk. Frontal append- 
ages lanceolate, resembling those of E. ornatus Holmes; both margins 
lobate, the lobes most pronounced on middle; usually rolled into a 
cylindrical form; inner surface of appendage and lobes denticulate. 
Second antennae: basal segment armed with a rounded tubercle at 
proximal end of inner margin; terminal segment as wide as basal 
segment at proximal end with a strong sinuous finger-like process pro- 
jecting inward from the inner margin near proximal end; this process 
is half as long as the segment that bears it and its tip is roughened ; 
terminal segment narrow in middle, enlarged and abruptly truncated at 
tip. 
Abdominal segments not narrowed in front or produced backward at 
their posterior angles, the last segment slightly wider distally than those 
preceding it. Penial appendages curved outward with teeth along distal 
portion of outer margin ; basal portions bearing denticulate processes 
that meet in the median line. 
Female: None of the lateral margins of the segments are produced 
posteriorly. The second antennae end is an acute process that is di- 
rected outward. 
Length of largest individual, a female; 21 mm. 
The types, six females and five males (Michigan Museum, No. 40527). 
were collected by the writer at Lincoln, Nebraska, April 20, 1899. This 
species was also collected at St. Louis during the spring of 1912. 
Eubranchipus gelidus (Hay). 
Through the kindness of Brofessor C. W. Hargitt the writer was able 
to examine six females and four males collected near Syracuse, New 
York (42313). As this species has never been figured four cuts are 
presented which show the male appendages and clasping organs as 
well as the peculiar processes on the last two pregenital segments of 
the female. 
Branchinecta packardi sp. nov. 
Male: Body slender; no lateral spines. Basal segment of second an- 
tennae produced and spiny at inner proximal angle; a prominent finger- 
like process with a tuberculated tip arises on the anterior surface near
