described is Bhazvania myrialepis, mentioned by Schmarda from Trinkomali (Ceylon). This 

 specimen has a length of 63 mm. and a breadth of 4 mm.; the number of segments amounts 

 to 220. The paleae, which cover the vvhole back, are g-olden-yellow, mixed with red; the middle 

 of the back is paler, its margins darker coloured. The ventral side of the body is red-brown. 

 The paleae are situated in a faintly curved row, 12 to 14 on each side of the back: in 

 the middle of the body they measure 0.5 mm. in length. They show 14 longitudinal lines, 

 that are dissolving by high power in small spines, standing upon prominent ridges. Presumably 

 the head was withdrawn, for Schmarda says : „the head is small, with 5 (?) antennae of the 

 same length ; eyes not visible". Forty years afterwards Gravier published an elaborate descrip- 

 tion of Bh. cryptocephala, based on three specimens, collected by Coutière near Djibouti. They 

 are somewhat smaller than Schmarda's specimens, for the largest one has a length of 25 mm., 

 and a breadth ot 2.1 mm., whereas the number of segments is 1 80 ; its colour is amber-yellow, 

 dark red-brown along the sides. The paleae are striated transversally and longitudinally and 

 moreover show three prominent ridges with a beaded edge. In these specimens also the head 

 was withdrawn and Gravier could only recognize in the median line (?) two oval spots, iden- 

 tified by him with eyes. Potts believes to have found the same species in the neighbourhood 

 of Zanzibar, though he observed some differences in the structure of the paleae and the ven- 

 tral setae. I think it very probable that Schmarda's worm also belongs to the same species, but 

 this cannot be settled without examining the typical specimen. In 1909, without knowing Gravier's 

 paper, I described my self a i)//(7Z£'a«M-specimen from Batavia, that in the structure of its 

 paleae and parapodia so much resembles Bhatv. cryptocephala^ that I believe it also ought to 

 be identified with this species.

At the above-named Station a small fragment was found of the variety of Bhazü. cryp- 

 tocephala, first mentioned by Potts from Zanzibar and therefore named after him ; it is charac- 

 terized by, (i) small irregular' spines on the tip of the paleae, and (2) a third kind of ventral 

 bristles, very slender, with long hair-like appendix, but always with a smooth edge.
