The proboscis, which is often ejected iu formalin solution, is large 

 and clavate, four-lobed at the end, 12 to 14'"™ long. 



Length, up to 15 to 90""" ; breadth, 10 to lo""'", in extension ; it often 

 contracts into hiuch shorter and broader forms.

 shallow watei'. Castle Harbor, at Waterloo, low-tide, under stones,

This species is here referred to the genus Discocells with some 

 doubt, for its anatomy has not yet been sufficiently studied. 



Trigonoporus microps V., sp. nov. 



Plate V. Figure 2. 



Body thin, usually long and narrow, very extensile and change- 

 able, the edges usually much undulated and very thin ; both ends 

 may be subacute in extension. When fully extended the body is 

 very nari'ow, the breadth being about one-sixth to one-eighth of the 

 length. 



Cerebral clusters of ocelli are lacking ; but numerous minute 

 ocelli are scattered over the anterior dorsal region and along the 

 anterior margins, becoming much more numerous and crowded into 

 several rows close to the anterior end. The stomach is very long, 

 extending through most of the length of the body, and it gives off 

 very numerous, nearly transverse, lateral branches, which are sub- 

 divided into numerous dendritic branchlets. 



Color of the bod}^ pale flesh-color or cream-coloi-, the stomach and 

 its branches showing through as rather darker pale ocher or 

 brownish markings. 



Length up to 5U or 60'"'" ; breadth, in extension, 5 to 10'""^. 



Castle Harbor and "The Scaur," undei" stones at low-tide; May

This species closely resembles T. cephalophthalma, of the Gulf of 

 Naples, (see Lang, Polycladen, p. 503, pi. ii, fig. 1), in form and in 

 the arrangement of the ocelli. The latter, however, differs in color 

 and, apparentl}', in the relative length of the median gastric cavity, 

 which is about one-third the total length, yet when more fully 

 studied they may prove to be identical. The internal reproductive 

 organs of our species have not been studied, so that its generic 

 position is not positively settled. I have placed it in Trigonoporus 

 mainly because of its close resemblence to the Naples species, as to 

 form of body and arrangement of the ocelli. In the latter the gas- 

 tric streak is white, bordered and continued by orange-brown, other- 

 wise the upper side is pale greenish gray.
