 surface pale purplish. The attached young, about 0.3 of an inch long in 

 extension, were slender, whitish, and subdiaphanous, with the brown intestine 

 showing through posteriorly.

 CLEPSINE ORNATA Verrill.

The specimens of this species originally described, although found 

 carrying young, were probably immature. Specimens of much larger size, 

 and having more numerous papillae, have since been obtained. They are 

 so different as to be easily mistaken for another species, but their young 

 have been found to agree with the original description. It is probable 

 that this and other species of Clepsine begin to breed long before they 

 become full grown, and that they live several years. The following is the 

 original description: — 



"Body somewhat depressed, rather broad and obtusely rounded pos- 

 teriorly, in extension tapering, but not slender anteriorly, about 1.25 inches 

 long. In contraction elliptical, and about 0.20 inch broad in the middle. 

 Back with a median papillose dorsal carina, and two similar ones midway 

 between it and the margins. Head broad, acuminate, whitish in front and 

 at the margins. Ocelli united into a single, small, transverse spot, situated 

 at the edge of the white area. Acetabulum moderately large, round ; about 

 half of its breadth exposed behind the end of the body. 



"A dark green line passes along the median carina, interrupted 

 anteriorly by several transverse, orange vittse, and farther back by some 

 pale orange spots; the first of the transverse spots or vitta? is pale orange, 

 and is just behind the white area of the head; this is followed by a trans- 

 verse greenish-brown one, which is succeeded by a longer transverse 

 orange one; farther back is another transverse vitta, or band, of the same 

 color. The posterior part of the back and upper side of acetabulum
