corpo, che qua si sviluppano i giovani vermi, i quali arrivati a certa grandezza per- 
forano dall’ interno all’ esterno le pareti del corpo per armidarsi sotto la cute. 
Quali sieno le loro peregrinaziono ulterior!, come arrivino a depositare le uova 
nella cavita addominale, sono quesiti impertanti bensi ma tali che soltanto qualche 
osservazione accidentalmente fortunata sara in istato di sciogliere. lo ho creduto 
necessario il pubblicare quetsi fatti affinche possano servire di traccia a qualche 
altro investigatore. 
Osservazione 3. Ho voluto dare un’ imagine tanto del verme nella vescichetta che 
isolate. 
Any generic diagnosis written for the 
genus Filaria should contain the major 
characters given above (p. 34) for Filaria 
martis. This species, which does not ap- 
pear to be rare, should be carefully re- 
studied for other characters; some char- 
acters of striking nature are almost posi- 
tively absent from F. martis^ otherwise 
authors would doubtless have mentioned 
them. While it is impossible to write 
a detailed diagnosis for Filaria until the 
type species is restudied, we are now in 
a position to determine some of its most 
important characters; and these we may 
safely take as minimum characters for a 
type subgenus Filaria {Filaria)^ even if 
not for the genus Filaria. 
Subgenus FILARIA Mueller, 1787. 
1787: Filaria Mueller, 1787, 64-67 (type by elim- 
ination, F. martis Gmelin, 1790, in sub- 
cutaneous, tissue of Mustela martes of 
Italy); from filum, a thread. 
1809: Filaraia Rudolphi, 1809a, 69, misprint 
1840: Filaire Lee, 1840a, 283, misprint. 
1877: ? Wuchereria Silva Araujo, 1877, Nov., 492, 
504, mentioned as Wuchereria filaria possi- 
bly a lapsus for Filaria wuchereria. 
1877: Filariu Magalhaes, in Silva Lima, 1877, 
Dec., 544, misprint. 
1884: Filaria Calmette, 1884a, 459, misprint. 
1904: Falaria Leidy, 1904a, 190, misprint. 
Subgeneric diagnosis. — Filaria: Very long, filiform vmrms. Cuticle unstriated 
(Alessandrini) and evidently without bosses. Mouth small, round, unarmed, ter- 
minal, without lips. 
Male: Shorter than the female; tail forms a spiral, and is provided with lateral 
cuticular alse and with both preanal and postanal, filiform, papillae, spicules unequal. 
Female: Vuh^ anterior, very close to the mouth. 
Type-species. — Filaria martis Gmelin, 1790.

Mouth; 6, 6', papillae; c, “pharynx;” 
d, “stomach;” e, e', intestine, with 
polj^gonal cells; /,/, genital organs; 
g, tail. Greatly enlarged. (After
