by him ( 30 , pp. 680-684) fits this specimen well. It is 
12 mm. long by 1*9 mm. wide. There are 37 wreath spines, 
15 dorsal, 6 on each side, and 5 on each venti'al lobe. In its 
anterior part the integument of the body is thickly covered 
with small spines, which gradually decrease in number 
towards the posterior end, and quite vanish at the level of 
the posterior testes. The tests are as broad as long, and 
very deeply incised, so that each is six-lobed. I follow” Dietz 
( 13 ) in placing it as E. revolutum Froel. 
Patagifer l)ilobus II. 
A single specimen of this species was obtained from the 
intestine of the black-billed spoonbill, Platalea regia. 
It was fixed in sublimate-acetic-alcohol, slightly flattened, 
stained with hmmatoxylin, and mounted whole. It measures 
17 mm. in length and 1*4 mm. in breadth anywhere behind 
the ventral sucker, except near the posterior end, where it 
narrows to a round blunt point; it is somewhat wider at the 
level of the ventral suckei*. Except that the lateral wreath 
spines are pointed at their outer ends, it agrees in all respects 
with the description given by Dietz ( 13 , pp. 417 — D9), and by 
Looss ( 30 , p. 685), for P. bilobus from Platalea leuco- 
r o d i a .

Typhlocoelum reticulare sp. n. (Figs. 5, 6, 7, 27-30, 
and 33.) 
Diagnosis. — Small, flat, leaf-like worms, about 4 mm. 
long. Integument smooth. Sucker very weak, with its 
opening ventrally placed. Intestinal limbs with short ceeca 
on their inner sides ; joined together by a transverse loop 
at their posterior ends. Excretory pore on the dorsal surface 
near the posterior end; vessels forming a ventral network.
