It is only after much hesitation that I refer these Httle Echini 

 to this Japanese species, but were they from Sagami Bay, 

 Japan, I should do so without question. All are small, and 

 only eight show the characteristic clypeate spines, but there 

 is at least one of these from each of the stations hsted below. 

 All the specimens agree in a greenish colouration, or at least 

 in having a greenish tinge, particularly on the actinal primaries 

 and in lacking the big globiferous pedicellariae characteristic 

 of the two following species. The largest specimen is 20 mm. 

 in horizontal diameter and comes from off Cape Pillar, Tasmania. 

 I have compared it with a specimen of the same size from 

 Japan, and while there are obvious differences, they are so 

 trivial that I cannot find a single good character, nor any 

 tangible combination of characters, which would justify calling 

 the two specimens by different specific names. The " Siboga" 

 took, in the East Indies, south of the equator, a cidarid which 

 de Meijere called G. hirsutispinus but which I beheve to be 

 G. clypeata, so that the occurrence of this species in both 

 Japanese and Tasmanian waters is not so improbable as at 

 first appears. Fourteen specimens.

These specimens are nearly all small, only four exceeding 

 25 mm. in diameter. The largest, 37 mm. in diameter, is a 

 good example of the species and shows the distinguishing 

 characters well. The two other adults (30 and 32 mm.) are 

 less typical, but are undoubtedly G. geranioides. Many of the
