Description : — " Body more or less oljviously cm'ved, tapering 

 nearly equally towards each extremity. Tentacles ten, two ventral 

 smaller. Anus with five teeth, made up of a calcareous network. 

 Pedicels in a distinct double row on each of the ventral ambulacra 

 and in a less distinct double row on the two dorsal ; smaller 

 pedicels are also to be found scattered over the five interambulacra 

 of the larger specimen, while in the smaller individuals the ventral 

 interambulacra seem to be almost naked. A single Polian vesicle 

 and madreporic canal present. Calcareous ring very slender, devoid 

 of posterior prolongations. Deposits more thinly scattered, of two 

 kinds ; smooth rods, typically with a hole in each slightly enlarged 

 end, thus resembling spectacles, but often of a more irregular 

 form, more or less curved, with several, often three, holes placed 

 at each end ; and here and there smootli plates with uneven, 

 undulating margin, and pierced witli a varying number of round 

 holes. The sui-faces of the plates and rods are not quite level, 

 owing to some very low, nearly inconspicuous elevations. Pedicels
