NO. 1560. PARASITES OF BERMUDA FISHES— LINTON. 91 



the latter making- a crenulate outline. The anal papillae are very small 

 and numerous; the exact number was not determined. Seen in lateral 

 view there appeared to be about 8 postanal and probably as many as 

 60 preanal papilhe. 



The above description was based on a specimen mounted in balsam. 

 The teeth and papilhe on the lips were nt)t very distinct. The teeth 

 appeared to be simple tubercular, and there appeared to be two papillte 

 on each of the lateral lips. 



Postanal region slender pointed. Other details are given under the 

 several hosts. This ascarid was found in three of tlie Bernuida tishes, 

 as follows: 

 Jjodianv-s fulvus punctdt nx. 



July 22, one. Dimensions in millimeters of specimen mounted in 

 balsam: Length, 7; diameter of head 0.12, at base of eso})lK)gus 0.3, 

 middle 0.3, at anal aperture 0.10; distance from anal apertui'e to pos 

 terior end, 0.21; length of jaw O.dlo, breadth 0. ()<);• length of esopha- 

 gus, 1.5, diameter of esophagus, anterior 0.12, middle 0.11, ])ase 0.11; 

 length of diverticuknn of esophagus 0,33, of intestine 0.1.5. 

 Epinephelus stria tus. 



July 11, live, females, from intestine. These worms were j^ellow- 

 ish, except at the extremities, where they were translucent white. 

 The jaws were broader than long, with rather wide transparent borders 

 and distinct branching pulp. Length, 12 to 11 nun. 

 Mycteroperca apua . 



July 21, one, male; length in balsam, (S mm. The postanal region 

 was rather more slender than in others and the esophageal diverticu- 

 lum was longer, but still shoi'ter than the esophagus. 



IMMATURE NEMATODES. 

 Plate 1, Htr. '1. 



These all appear to belong to the same species and are proljably 

 3^oung stages of the foregoing, Axcarix^ species, from Bodi.anus^ etc. 

 They are characterized by having a very short diverticulum of the 

 intestine and a longer and more slender diverticulum of the esophagus. 



These inmiature forms were found in the following hosts: 

 Bodian us ftdrus piincfdtns. 



July 22, few, very small. Numerous small cysts containing amber- 

 colored waxy secretion were found on the viscera of the fish taken on 

 l)oth the 22d and 23d. These were 0.7 mm. and less, in diameter. 

 A minute nematode was obtained from one of these cysts. 

 Eplnep/u'I IIS iiiacidosus. 



July <S and 11, one on each date. Dimensions, in millimeters, life: 

 Length, 5; length of esophagus 0.75, of bulb at base 0.04, of diverti- 

 culum 0.45; intestinal divei-ticulum ver}^ short, about equal to the
