identity. Their condition is so poor, it is not possible to tell the number 

 of tentacles, but on the better preserved one, only thirteen can be counted. 

 The calcareous particles are exactly like those described and figured by 

 Ludwig. The series of pedicels in the mid-ventral ambulacrum is evident 

 but on neither the dorsal nor ventral surface are the ambulacral outgrowths 

 nearly as numerous as in Ludwig's description. It is possible however that 

 this difference is a matter of age, but the genital glands are in two well 

 developed tufts, utterly unlike the elongate organs figured by Ludwig for 

 Lcetmophasma, and it is more difficult to believe that this is an effect of 

 immaturity. I think it quite probable therefore that these specimens are 

 not fecundum and very possibly not Lcetmophasma, but in view of their 

 condition I am not willing to describe them as a new species.

Pannychia moseleyi.

Although none of the specimens before me is in good condition, several 

 permit a more or less accurate estimate of the number of ambulacral ap- 

 pendages. This estimate shows that these individuals are intermediate 

 between Theel's typical specimens and Ludwig's proposed variety henrici, 

 and makes it probable that the latter name does not cover a constant form, 

 and need not be retained. The largest specimen in the present lot is about 

 160 mm. long and has twenty tentacles.

There is a single specimen, 125 mm. long, in very good condition, of 

 this wide'y distributed species.
