ON A BHAWANIA-SPECIMEN. 



segment and a tapering distal part, nearly of the same 

 length. This terminal portion is provided on its surface 

 with small tubercles and shows in its basal region several 

 strongly refringent glands. The ventral cirrus like- 

 wise is articulated, but it has a short conical basal segment; 

 its distal part is dilated at the base and contains also 

 numerous glands. A pair of slender anal cirri are present, 

 extending somewhat beyond the posterior segment. 



Whether our Batavia-worm is specifically distinct from 

 the Bhawania myrialepis of Schmarda, from Ceylon, is not 

 easy to decide. The dimensions of the last-named species 

 are much greater, its length being 63 mm. and its breadth 

 4 mm., whereas the number of segments amounts to 220; 

 the paleae are of a gold-colour mixed with red, and the 

 belly is reddish brown. Regarding the head Schmarda 

 states: it is small, provided with five antennae of the 

 same length and wants the eyes; but I have some doubt, 

 that his description as well as his figure is not exact, 

 perhaps because he could not clearly distinguish it, like as in 

 our specimen. On the contrary the cephalic lobe of Paleanotus 

 agrees with that of Chrysopetalum in the presence of 3 

 antennae and 2 pairs of eyes. 



For a longtime there reigned a good deal of uncertainty 

 about the real characters and the systematical position of 

 Palmyra, because, as rightly stated by Racovitza 1 ), the 

 descriptions of the different authors were very divergent 

 and discrepant. By the investigations of Grube 2 ) and Mc. 

 Intosh we now have a better knowledge of the structure 

 of Palmyra aurifera and it is proved by these authors 

 that Palmyra is distinguished from Chrysopetalum and Palea- 

 notus (and Bhaiuaniat) not only by another structure of 

 the head (stalked eyes, a single unpaired antenna) and by 

 the parapodia having simple ventral bristles, but also by
