So far as we have been able to find, Leuckart (1863, 289, fig. 80) 
is the only other helminthologist who has examined this parasite ; he 
reexamined part of Weinland’s original material and concluded that 
it represented a variety of Tdenia mediocanellata ; in his later work 
(1880, 605-606, fig. 272) he refers to it as Taenia saginata var. ahi- 
etina. Not altogether in harmony with Weinland’s description, 
Leuckart’s figure of the uterus shows a number of the lateral pouches 
of the uterus as branched ; he gives about 40 branches each side. 
All later references to the parasite are either based directly upon 
the conclusions drawn by Weinland and by Leuckart, or are opinions 
expressed on basis of the data given by these two authors. 
Diesing (1864a, 369) considers abietina a variety of 1\ saginata. 
Blanchard (1886a, 362-363, fig. 238) considers it as “ a simple va- 
riety of T . saginata.'^’’ 
Braun (1903, 3 ed., 224) thinks it a “7". saginata., with uterine 
branches somewhat more thickly set; ” he also suggests (p. 229) that 
it may possibly be identical with T. confusa Ward. 
Stiles (1906, June, 31-32, figs. 35-38) recognized the form provi- 
sionally as a subspecies of Taenia saginata. He republished Wein- 
land’s and Leuckart’s illustrations of the worm. 
Reexamination or okiginal material. — Segments: The speci- 
men consists of only 5 gravid segments, which are in very poor state 
of preservation. At the time it came into our hands it was com- 
pletely dried out and, naturally, brittle. It was soaked in very weak 
alcohol, which was gradually increased in strength ; then it was trans- 
ferred to alcohol glycerin, the alcohol was allowed to evaporate, and 
the worm eventually mounted in glycerim jelly. Because of its hav- 
ing been dried a detailed study of the anatomy is of course excluded. 
The segments measure as follows : 
About 12 mm. long by about 2 mm. broad. 
About 12 mm. long by about 2 to 3 mm. broad. 
About 12 mm. long by about 2 to 2.5 mm. broad. 
About 11 mm. long by about 2.5 mm. broad. 
About 11 mm. long by about 2.5 to 3.5 mm. broad. 
Genital pores. — The genital pores are irregularly alternate and are 
caudad of the equator of the segment^ — more exactly, about five- 
eighths from the anterior margin. 
Uterus. — No remnants of the genital glands can be seen, and it is 
scarcel}^ possible to count the lateral branches of tlie uterus; these 
are, however, numerous. 
Eggs. — The uterus is crowded Avith eggs, which vary in size from 
31 to 37.5 by 30 to 33.9 /x. An average of 31 embryophores gave 36.27 
by 32.09 /x; the usual length (21 cases) was 37.5, the most frequent 
breadth (11 cases) 31.9 /x.
