diameter. They uccur in the pusteriorniust parts wliich extend 

 on the dorsal surface aljout half a centimetre and on the 

 ventral surface about 2 cm., in front of tlic posterior marginal 

 border. ISo far as 1 can ascertain, they are not found in thc^ 

 lateral margins of the body, nor iu the marginal border in front 

 of the head. Supporting rods (n) are found in the pedicels 

 and pa{)illae. They are large in the ventral pedicels, the smallest 

 measuring 0.38 mm. They arc roughened at the ends. In the dorsal 

 l)apillae the rods are shorter and more slender, being only 0.17 

 mm. long. Well developed end-plat(3S are found in the ventral 

 pedicels. They are imperfect in the dorsal i)aiiillae. 1 can find 

 none in the marginal 23a;[)illae. 



Bemcv'Jis : — This species is very close to Batlu/plofcs rubicundus 

 Sluitee, but there are some differences : — ■ 



(1) The most important difference lies in the presence of 

 the large irregular calcareous bodies in the posteriormost parts 

 of the body in the present species. Sluiteu makes no mention 

 of such bodies in B. ruhicundua. 1 tliink it barely possible that 

 Sluiteu overlooked these bodies. 



(2) In the new species there are 'JO tentacles, all alike in 

 size, while for Ji. rubicundus it is distinctly stated by Sluiteu 

 that there are only VI sliort tentacles, of wliich the two ventral 

 ones arc much smaller than the others. 



(3) The color of liody in my species is carmine red, while 

 B. rubicundus, to judge from the sketch given by Sluiteu, is 

 brick red. 



(4) The longitudinal muscle is distinctly divided into 

 two in my species, while it is said to be undivided in B. 

 rubicundus. 



(5) Marginal papillae are much larger than dorsal papillae
