A. Subgenus HAMULARIA Treutler, 1793. 
1793: Hamularia Treutler, 1793, 10-13 (m. lympliatica— equina) . 
1800: Tentacularia Zeder, ISOOa, 5; Hamularia renamed. [Xot Tentacularia Bose, 
1797.] 
1840: Haiilarialu,ee, 1840a, 282; misprint. 
Hamularia lympliatica has recently been identified with Filaria 
equina. The mouth, tail, and certain other characters of this worm 
differ so radically from Filaria martis that equina can scarcely be 
placed in the typical subgenus Filar ia. It ma}" at present be admitted 
to only subgeneric rank (for the sake of conservatism), but with the 
statement that it will probably soon be raised to generic rank. For 
this group the generic name Hamularia is at present available. 
In this connection it should be stated that for years authors were 
not in accord as to the zoological position of Hamularia. Some authors 
have thought that the type Hamularia lympliatica is identical with 
Strongylus longevaginatus { — 2Ietastrongylus apri). Leuckart first 
thought it was an Ascaris mystax { = Toxocara)^ but nearly all recent 
authors consider it a Filaricu while Linstow (1902, 222) and Braun 
(1903, 276) have accepted it as identical with Filaria equina. On 
authority of this latter interpretation, Hamularia.. may be considered 
as an available name for the subgenus in which Filaria eequina is 
placed, unless it be shown that Linstow and Braun are in error in their 
conclusion. On their authority I accept their synonymy, and this 
acceptance makes it obligatory on me to use Hamularia in this place.
