NO. 1560. PARASITES OF BERMUDA FISHES— LINTOX. 101 



Found in two of the Bermuda fishes. 

 Ballstes vetula. 



July 27, one, from C3^st in intestinal wall. The intestine of the fish 

 was thickly beset throughout its length with chalky c^'sts. A number 

 of these cysts were removed and left over night in sea water. A^'hen 

 they were examined the following morning nothing was found in them 

 but a pulpy, granular mass. The larval tetrarhj^nch was found free 

 in the dish with the cysts. The scolex was still active, the bothria 

 constanth' changing their shape, and the proboscides at frequent 

 intervals were protruded and withdrawn. This action was somewhat 

 rythmical. The hooks w^ere characteristic of the species; the collar 

 was elongated and conical. Dimensions, in millimeters, life: Length 

 1.8, of bothria 0.75, of collar 1.0.5; breadth of head, maximum 0.60, 

 of neck, behind bothria 0.52, at posterior end 0.22; diameter of pro- 

 boscis 0.01. 

 Paran thias furcifer. 



Jul}^ 29, one, from a small degenerate cyst on viscera. 



SCOLEX POLYMORPHUS Rudolphi.

Found in three of the Bermuda fishes: 

 Ahudefdvf mMitilis. 



July 31, few, in alimentary canal. They were small, the bothria 

 without costaj. There were two red pigment spots in the neck and 

 numerous calcareous bodies in the parenchyma. Length 0.00, breadth 

 0.27 mm. 

 Ep inephelus niaeulosus. 



July 8, two, in intestine, small; prominent terminal sucker; bothria 

 without costa? and no pigment in neck. Length 0.9, breadth 0.2 mm. 

 Ephicphelus str!at uh. 



July 11, about 60 found after going* over washings from the 

 alimentary canal of three large groupers several times. These were 

 small, with two red pigment patches just behind the head, and no 

 costge on the bothria. In contracting there was a tendency to lengthen 

 the posterior end of the bod}' into a slender, pointed tail, the head, 

 at the same time becoming nearly globular. Most of them, when 

 contracted, are transversely wrinkled. A contracted specimen was 

 0.6 mm. in length and 0.1 mm. in breadth. August 3, two cysts on 

 viscera.
