The observations of these authors do not fully agree. Salensky confirms 
generally the statements made by H. Nitsciie [Zool. Rec. xii. p. 212]. 
He refutes O. Schmidt’s determination that the so-called bud originates 
from an egg, and describes in the adult animal an organ of sense (a 
small elevation set with stilf hairs) which he compares with the so-called 
uiilomui of tliu Uoilfcra, 0. Vogt status that tho soxos aro separate on 
diifuront individuals, and describes the first formation of the egg and tho 
origin of the bud out of the ectoderm ; he compares the adult Loxosoma 
morphologically with Pedicellina, and states that it is chiefly distin- 
guished by being vertically compressed, the tentacular crown placed on 
the ventral side, the more delicate substance of the body, and the solitary 
semi-parasitic life on Annelids, Sipunculids, &c. Vogt and Salensky agree 
in the statement that the number of tentacles increases in the same indi- 
vidual with age j from 12 to 18, according to the former. Vogt states that 
the species observed by himself had no pedal gland ; Salensky points out 
that in two observed by him, it was wanting in the adult, but present iu 
the young animal.
