Two distonies, found .Inly 28, 1899. The following description is based on a memorandum sketch 

 of the hvinj; worm and on a mounted specimen. Unfortunately one of the .specimens was in bad 

 condition when it was found. Boily ovate-elliptical, depre.-^-^ed. with a short, retractile cau<lal aiijwn- 

 ilix; neck short. (»ral sucker subterminal with somewhat triangular aperture, a little broader than 

 long. Pharynx siihglnbular immediately follnwiiig the oral sucker. <F^(«])hagus slicirt. Intc-itinal 

 rami simple elongate, extending to but nut entering the appendix, .\cetaliulum at alxnit the anterior 

 fifth or sixth of the body, a little broader than long, in ventral view, much larger than oral sucker, 

 aiHjrture circvilar in life, transverse in alcoholic specimen. Cirrus jxiiich an<l seminal vcscicle K-hind 

 acetabulum; the cirrus ])a.«ses to the left of the acetabulum and ojjens alxmt half way lietween the 

 suckers on the median line near tVie u'sophagus. Testes two, large, snbglobular, placed transversely 

 lictiiiid the acetabulum, from which they are separateil only by the cirrus pouch and .«eminal vcscicle. 

 I Ivary globular, snuvller than the te.-iles on median line behind the testes an<l clo.^e to them. Vitelline 

 illands, two slender, convnluteil tubular organs mai-ginal to right ami left of ovary. No ova were seen 

 in I lie living specimen and the uterus Wiusnot seen.

 3.07; diameter, anterior l(..54, at acetabulmii 0.92, median 0.92, Mear posterior 0.."iO; oral sucker, length 

 0.24, breadth 0.24; acetabulum, length 0.41, breadth 0.43; diameter of testis, 0.4(i; pharynx, length 

 0.14, breadth 0.14; le.sophagus, length 0.07, breadth 0.08. 



Dimensions of specimen mounted in balsam, in millimeters: Length, not inclmling appemlix, 1.9; 

 length of appendix, 0.32; brejidth of body, anterior 0.1 1>, median 0.77, posterior 0.29; of appendix 0.17; 

 (iral sucker, length 0.13, breadth 0.14 (in the other (damaged) specimen the.-ie dimensions are 0.17 and 

 0.20); acetabulum, length 0.. 32, breadthO.34 (0.45 and 0.41 in the other); pharynx, length O.OS, breadth 

 0.09 (0.09 and 0.15 in the other). 



In the mounteil specimen what I take to U' an ovum lying dors;il to one of the te.<tes is 0.035 iuid 

 0.021 nmi. in the two principal diaiiietei-s.

Seaweed, liyilri>id stems, bryozoa, tunicates, anneliils, small cnislace^uis of various kinds (('npnllo, 

 shrimp.-!, |.tc. ), univalve molUisks found in stomach and intestine — in short, just such food as the lish 

 would get by browsing on the nuiterial which grows on wharf piles and similar jilaces.
