EUGYRA. 69 



The digestive organs in E. globosa, are similar to 

 those of E. arenosa which are described above. The 

 intestinal loop is, however, shorter than in it, and that 

 formed by the rectal portion is so shallow that it can 

 scarcely be said to exist. No portion of the intestine 

 is wide, and the upper or rectal half is somewhat con- 

 stricted ; the liver is of a black-green colour, and forms 

 a large subquadrate mass, entirely concealing the 

 stomach overlying it apparently on both its right and 

 left sides ; there is a small supplementary lobe placed 

 in contact with, and immediately below, the principal 

 mass. 



The reproductive organs are confined to the right 

 side ; there is only one mass combining both elements. 

 This lies on the inner or left-hand surface of the 

 intestine, the posterior portions passing into the great, 

 or first, or lower loop ; the anterior extremity crosses 

 the intestine and terminates in the second, shallow 

 loop formed by the rectal portion of the tube. There 

 is thus, when seen through the right side of the mantle, 

 the appearance of two distinct generative masses. The 

 female organ is an elongated sac with the posterior end 

 doubled upon itself, and, when filled with mature eggs, 

 is of a bright yellow colour. The testis, which is of a 

 dull purple hue, when observed in specimens preserved 

 in spirit, is composed of a great number of irregular, 

 elongated vesicles or caecal tubes, which are combined 

 into a dense mass that enfolds and nearly conceals the 

 posterior portion of the ovigerous sac, and overlies to 

 a great extent the anterior portion, which is rounded 

 in front, and, along with the ovary, abuts against the 

 intestine a little way below the anal termination ; and 

 here the oviduct, which is a long nipple-like tube, 

 opens into the cloaca. The reproductive organs in 

 E. globosa do not differ in any important character 

 from the above.
