POLYCLADS OF W. INDIES AND FLORIDA — ^HYMAN 125 



Family Cryptocelidae Laidlaw, 1903 

 Anandroplana, new genus 



Definition: Cryptocelidae of elongate oval form; band of marginal 

 eyes completely encircling the margin; pharynx long, much ruffled; 

 male apparatus close behind the pharynx; lacks seminal vesicle, 

 prostatic vesicle, and penis papilla; male apparatus excessively muscu- 

 lar; Lang's vesicle wanting. 



Type species: Anandroplana muscularis, new species.

Figures 83,6; 84, a 



Material: One specimen from the Smithsonian-Hartford Expedi- 

 tion of 1937 to the West Indies. 



Form: Elongate oval with rounded ends (fig. 83,6), 17 mm. long 

 by 7 mm. wide; margins somewhat ruffled, indicating some con- 

 traction. 



Eyes: Distinct cerebral and tentacular clusters are present, each 

 of a considerable number of eyes (fig. 83,6) ; the cerebral eyes form 

 oval groups to either side of the brain, of 20 to 25 relatively large 

 eyes each ; the much smaller and more numerous (40 to 60) eyes of the 

 tentacular groups extend forward between and beyond the cerebral 

 clusters. The band of marginal eyes completely encircles the margin; 

 it consists of rather small eyes, as usual in the family, and diminishes 

 in width posteriorly. 



Color: Preserved specimen appears dark brown. 



Digestive tract: The rather large, elongated, and much ruffled 

 pharynx is rather centrally located (fig. 83,6) ; a distinct circular open- 

 ing just behind its last fold was taken to be the mouth. A similar 

 position of the mouth occurs in another cryptocelid genus, Ommato- 

 plana Laidlaw, 1903a. Because of the dark color no further details 

 of the digestive tract were evident in the specimen. 



CopULATORY apparatus: The postphar3Tigeal region was removed 

 and sectioned sagittally. It was found in bad condition, with 

 many cracks and tears but all parts of the copulatory apparatuses 

 seemed to be present. The male apparatus lies close behind the 

 pharynx so that the last folds of the latter are in contact with the 

 antrum wall. A sagittal view of the apparatuses, insofar as they 

 could be ascertained, is given in figure 84,a. The male apparatus is 

 unusual in that it lacks seminal vesicle, prostatic vesicle, and penis 

 papilla. It appears to consist wholly of a very large antrum with 

 irregular waUs excessively provided with muscles. The muscles seem 

 to occur in lengthwise cords united with each other in a weblike
