ANNELIDA POLYCHAETA. 167 



large epitocous examples it becomes obvious, that by the 

 lack of the chitinous investment the long ridges are broken 

 up in some irregular pieces. It may be concluded from this 

 case, how difficult it is to recognize the real arrangement 

 of the paragnathi , when having only a single specimen at 

 his disposal. Though these individuals show great resem- 

 blance to N. Jloridana Ehl. l ) and N. atlantica M'Int. 2 ) , 

 I hesitated to identify them with one of those species. In 

 N. jloridana the lateral patches of paragnathi in group III. 

 seem to be absent, and the tentacular cirri are also much 

 longer, reaching to the 11th segment; according to Lan- 

 gerhans' description 3 ) , who examined this species at the 

 coast of Madera, it should have »Gestalt und Vertheilung 

 der Borsten" like in N. cultrifera, whereas in our speci- 

 mens there occur no heterogomph setose bristles in the 

 ventral lobe. N. atlantica also wants the lateral paragnathi 

 of group III; moreover in this species the posterior feet 

 seem to have the dorsal setigerous lobe (» second lobe" Mac 

 Intosh) larger than the superior ligule (» superior lobe" Mac 

 Intosh) , quite opposite to our specimens. 



JMeveis malayana, n. sp. (Plate 8, figs. 4 — 7). 



Epitocous form. The largest specimen 9 cm. in 

 length, and 6.5 mm. in breadth at its widest part; the 

 number of segments amounts to 150 or 160. Cephalic lobe 

 about as long as broad ; antennae half as long as the head. 

 Palpi with a small terminal boss , their basal part with an 

 annular notch; they are about twice as long as the anten- 

 nae. The antero-posterior diameter of the buccal ring only a 

 little longer than that of the succeeding segment; all ten- 

 tacular cirri longer than the palpi , the longest of them 

 reaching to the 6th segment or farther backward. The 

 change of the feet commences in the cT at the 21st seg-
