about midway between the middle and the edges ; outside and 

 between these are numerous small specks of the same color. A 

 median pale gastric streak extends from the ocelli to near the pos- 

 terior end ; it is usually bordered by a deeper colored, salmon or 

 light orange band. 



The stomach is long and narrow, occupying most of the length of 

 the body behind the eyes. It gives off, mostly at right angles, a 

 large number of narrow, lateral, dendritic branches. The pharynx 

 is not very long, subcentral, lobulated. 



Length in extension, up to 30 or 40'""" ; breadth, 6 to 8™™, but it 

 often contracted to a shorter and broader form. 



Under stones and dead corals, and in their crevices, at low-tide. 

 Long Bird Island, April 19th and 29th. It is a very active species 

 and ci'eeps rapidly into holes and crevices, when disturbed. 



This closely resembles, in color, general appearance, and in the 

 cerebral eyes, the Leptoplana Alcinoi of the Bay of Naples, as 

 figured by Lang (Polycladen, p. 486, pi. ii, figs. 2 and 5). But our 

 specimens appeared to have a row of small, anterior marginal ocelli, 

 that are not present in the former. 



Discocelis cy clops Y., sp. nov. 



Plate V. Figure 1. 



Body usually much elongated, rather narrow, with thiii, more or 

 less undulated margins ; anterior margin usually obtusely rounded ; 

 j)OSterior end often tapered. 



The two cerebral groups of ocelli are semicircular or semiellipti- 

 cal and very close together, so that they seem to form a single, 

 rather conspicuous, rounded or elliptical eye, of larger size than 

 usual in this group. Around the front margin there are also two or 

 three rows of minute ocelli, which extend somewhat farther back 

 than the cerebral grou])S. 



Color of the body usually pale, translucent flesh-color or pale 

 cream-color, but nearly white toward the margins ; there is a rather 

 wide median dorsal stripe of orange-bi'own, made up of minute 

 round brown specks ; similar specks are scattered over the whole 

 surface, except near the edges, which are pale and translucent. 



One specimen was, in general, I'eddish brown, due to the color of 

 the dendritic gastric branches showing through. Another was 

 nearly white, specked with orange. The dark median gastric stripe 

 is often bordered with whitish. 



The mouth is far forward, only a little behind the ej^es.
