five V-shaped series within the papular area ; but on the ridge 

 of the arms the plates do not show any regular arrange- 

 ment. Except for the very small plates close to the margin of the 

 body and those that are found elsewhere among other larger 

 plates, each plate bears some 7-12 short pointed spines, which are 

 mostly covered over by a tumid membrane in alcohoHc specimens. 

 A few plates bordering on the madreporite are usually larger than 

 others and may bear more than 12 spines, wliicli are also slight- 

 ly longer than those of other plates. The papular pores are strictly 

 isolated and are absent for a certain stretch along the margin of the 

 arms, where the arrangement of the plates in longitudinal rows is 

 especially distinct. 



The madreporite is conspicuous and round and is covered 

 with meandering grooves. 



I have the pleasure of naming this species in honour of my 

 fi'iend. Dr. F. A. Batiiek of the Natural History Department of 

 the British Museum. 



I have specimens of this species fi-om Tokyo Bay, Misaki, 

 Miyazu, Kashiwajima (Tosa) and Shimabara (Hizen).

The body is very tliin and translucent, the margin is very 

 lightly scooped out, so that the outhne is nearly pentagonal. The

1) According to Bell and Flsher the vnlid post-Linnn?an name for this genus is Aixsero-

 Pcdmipes, however, -nas not used by a Linnsean -writer until a year after Anseroiwda Naedo. It 

 seems somewhat discouraging in the first years of the twentieth centiu-y to be obliged to call
