GOEZIA MINUTA, new species 

 Plate 11, Figures 2-4 



Speci-fiG diagnosis. — Body 3.1 mm long, nearly cylindrical, bluntly 

 rounded at head end, bluntly conical at caudal end, and slightly 

 narrower at end of anterior third of length than either before or 

 behind this region (pi. 11, fig. 2). Maximum diameter 280//,. Cuticle 

 provided with rows of spines for entire length. Spines largest and 

 rows farthest apart in second fourth of body length, where they are 

 spaced as much as 22/i apart. Just behind head annulations only 6/x 

 apart; in the middle esophageal region and again in third fourth of 

 body length, about lo/i, apart; much closer in posterior region. In 

 anal region the spines minute and directed forward instead of back- 

 ward. Lips provided with prominent lateral papillae. Diameter 

 across lips 110/x. Body constricted behind lips to diameter of 85^11. 

 Caudal appendage bluntl}^ rounded, about 28/^, long and 13/x broad 

 (pi, 11, fig. 4). Esophagus 360ft long, cylindrical, about Goju in 

 diameter for two-thirds its length, then widening out to diameter of 

 about 90ju. Esophageal appendix a long, narrow tube about 850/* in 

 length (pi. 11, fig. 3). Anterior cecum of intestine about ISO/t long 

 and 115/1 broad. Spicules approximately equal, about 315ju, long. 

 Cloaca about 45/a from posterior end, exclusive of caudal appendage.

Location. — Stomach. 



Locality. — Galveston Bay, Tex.

Remarks. — Only a single specimen, a male, has been found. Four 

 of the five species of Goezia hitherto described were described in the 

 early days of parasitology, and the descriptions are entirely inade- 

 quate from a modern point of view. The only well-described species 

 is G. gaviaJ'idis Maplestone, 1930, and only a single female of this 

 form was found. It is by no means certain that the form here de- 

 scribed is not identical with some of the earlier species, but it would 

 not be possible to identify it with any one of them at present. It 

 seems best for the present, therefore, even though the name may 

 eventually fall into synonymy, to consider it a distinct species. 



Family CUCULLANIDAE Barreto, 1916 



DICHELYNE FASTIGATUS, new species 



Plate 11, Figures 5-7 



Speci-fiG diagnosis. — Small, fairly stout nematodes, with body 

 tapering fairly evenly in both sexes from esophageal region to tail. 

 Cuticle in cephalic region thickened to about 30/*. Female 4.6 mm
