PARASITES OF BERMUDA FISHES— LINTON. 99 



many different shapes and sizes, hut on account of the siniihirity of 

 the hooks, which make up the several lon<^Mtu(linal rows, the general 

 effect is that of uniformity and symmetry. There is some resem- 

 blance in the ai'rangement of the liooks to that of Ii. .s/feclcsioH, par- 

 ticuhirh' in the case of one of the longitudinal rows, where the small 

 hooks of which it is composed are placed ])y twos on account of the 

 lengthening of alternate intervals l)etwcen the hooks of the row. A 

 characteristic feature of this species is the distinctness of the longi- 

 tudinal rows of hooks. There was no indication of segments. Dimen- 

 sions given below. 



NOTES ON HABITATS. 



Epin('phelus inacnloHUs. 



July 29, one clavato cj^st from viscera, length 28 mm. Bothria 

 with raised borders and I'oticulated surface; neck linear but may 

 present irreguhirities due to contraction. Dimensions of larva in 

 millimeters, life: Length 20; bothria, length 0.75, breadth (».60; 

 diameter of neck, anterior O.-io, at ]>ase O.GO; ])ul1)s, length 1.20, 

 breadth 0.21. The following additional measurements are from the 

 mounted specimen: Length 20; head, length 0.00, breadth (bothria 

 spread apart) 0.90; length of head and neck 5.7; prol^oscis, length, 

 approximate, 1.05, diann^ter neai" base, excluding hooks 0.036, includ- 

 ing hooks O.OG. The hooks were denser and longer than in R. specio- 

 siuii^ and the proboscides coiled into close spirals when everted. 

 Epinephelus striatus. 



July 18, four cysts from viscera. One larva measured HO mm. in 

 length. In a mounted specimen, the bothria being seen in marginal 

 view, the length of the head is 0.60, the breadth 0.82 mm. The neck 

 is linear except in front of the bulbs, where it is swollen, a condition 

 evidently due to unequal contraction. 



Parmithias fureifer, 



July 29, four dark-brown cysts of various shapes. One of the 

 larvae differed from the others in that the outline of the head was 

 somewhat triangular or cordate instead of orbicular in corresponding 

 view.

 fishes.

July 14 and 22, few on each date from cysts in walls of stomach and 

 intestine. The cysts were small, oval, white; when compressed they 

 revealed the larva in its blastocyst.
