DIGENETIC TREMATODES — MANTER AND VAN CLEAVE 335 



girellae is probably most similar to H. kyphosi Manter, 1947, and 

 H. ohtusus (Linton, 1910) from Tortugas, Fla. It differs from 

 H. ohtusus in its long posttesticular space, in the spherical shape 

 of the seminal receptacle, in lacking distinct vitelline follicles, in 

 the interruption of the vitellaria opposite the testis, and in shape 

 of the eggs. It differs from H. kyphosi in its unlobed ovary, rela- 

 tively larger acetabulum, elongated testis, interrupted vitellaria, 

 and smaller body size. 



Family MONORCHIDAE 



Genus PROCTOTREMA Odhner, 1911 



PROCTOTREMA LONGICAECUM Manter, 1940 



Host. — Anisotremus davidsonii (Steindachner),' California 



sargo. 



Location. — Intestine. 



Number. — Two. 



Discission.— This species is known hitherto from Anisotremus 

 interruptus (Gill) from the Galapagos Islands. 



Family HEMIURIDAE 



Genus APONURUS Looss, 1907 



APONURUS TRACHINOTI Manter, 1940 



Host. — Porichthys sp.^ 



Location. — Stomach. 



Discussion.— A single specimen agrees with the description of 

 A. trachinoti except in one respect: the eggs measure 30 to 32/^ by 

 13^ rather than 25 by 10/x. Since our specimen is somewhat larger 

 (1.77 mm. long) and no other differences could be seen, it is felt 

 a new species should not be named. Characteristic features are the 

 shape of the egg (pointed at one end), ceca not reaching the pos- 

 terior end, and the relatively small acetabulum (slightly less than 

 twice the size of the oral sucker) . 



Genus BRACHADENA Linton, 1910 



BRACHADENA PYRIFORMIS Linton. 1910 



Hosts. Anisotremus davidsonii (Steindachner),^ California 



sargo ; Porichthys sp.^ 

 Location. — Stomach.

' In the field this host was identified as Porichthys notatua Girard. Specimens were not saved 

 for later verification, but it seems probable that the hosts were the locally more common Porich- 

 thys myriaster Hubbs and Schultz, which had been recognized only a short time when this study 



was in progress.
