POLYCLADS OF W. INDIES AND FLORIDA — HYJVIAN 127 



is conjectured that the sperm ducts enter the anterior end of this 

 prostatic region but they could not be traced in the specimen. 



The female apparatus had suffered less damage than the male 

 apparatus but it had one bad crack. The female gonopore lies far 

 behind the male pore (fig. 84,a) and leads into a tubular antrum that 

 soon expands into a vaginal chamber receiving some glandular secre- 

 tion. This chamber is succeeded by a horizontal tube that presumably 

 springs from the roof of the chamber, but a crack here made it im- 

 possible to trace the connection. Tliis tube extends posteriorly and 

 terminates in a rounded vesicle that was at first thought to be a 

 Lang's vesicle, but, as it is surrounded by eosinophilous glands and 

 receives abundant secretion, it seems necessary to conclude that it is 

 the proximal part of the vagina. The oviducts could not be traced 

 satisfactorily but they appeared to enter the ventral wall of this 

 sacciform expansion. Between male and female gonopores the body 

 wall musculature is greatly thickened and this musculature continues 

 along the female antrum and fu-st expansion of the vagina. A large 

 mass of cement glands extends from this expansion backwards to and 

 around the proximal chamber of the vagina, and also from the vagina 

 forward up to the male antrum. 



Distribution: Collected by W. L. Schmitt off Puntilla Point, 

 Puerto Rico, at 3}i fathoms on a bottom of broken shell, broken 

 coral, and mud on Mar. 29, 1937. 



Holotype: Anterior part as whole mount, postpharyngeal region 

 as serial sagittal sections (seven slides) deposited in the U. S. National 

 Museum, No. 24632. 



Anandroplana portoricensis, ne>v species 



Figures 84,6; 85,a 



Material: One specimen presented by W. G. Hewatt. 



Form: Elongate oval, rounded anteriorly, bluntly pomted poste- 

 riorly (fig. 84,6), 32 mm. long by 15 mm. wide, alive, extended. There 

 is a large tear on one side of the rear half of the specimen but fortu- 

 nately this did not involve aii}^ part of taxonomic importance. To 

 either side of this tear occur several large balls that are probably 

 of parasitic nature, but sections of them did not serve to elucidate 

 their identity. It seems most probable that they are trematode 

 metacercariae but no suckers were found. 



Eyes: Tentacular eye groups are wanting. The cerebral eyes form 

 a single triangular cluster (fig. 84,6) ; anterior to this cluster, loose 

 frontal eyes extend on each side towards the marginal eyes without 

 reaching them. The marginal band of eyes completely encircles the 

 margin, diminishing in width posteriorly (fig. 84,6). All of the eyes 

 are unusually large and conspicuous for a cryptocelid.
