8. M. eremita n. sp. 
Three veiy poorly preserved specimens of this species were 
examined. They were taken from galls on a Challenger specimen 
of Metacrinus moseleyi^ Carp. The original label alludes to PI. 44 
Fig. 1 of Carpenter's work on the Crinoids of the Challenger 
Expedition and gives »Station 214« (south of the Philippines) as the 
locality. Each cyst is a slight thickening and resembles somewhat 
the cyst of M. pentacrini. It implicates only 3 or 4 joints of the 
arm and the basal segments of the adjacent pinnules as in that species. 
The irregulär opening of the cyst is sharply defined and the outer 
surfaces of the affected joints are irregularly granulated. Each cyst 
contains but a single Myzostome which is of a drab color. One of 
the somewhat distorted specimens is shown from the dorsal and 
ventral side in PI. 12 Figs. 39 and 40. These figures show that the 
dorsal reflection of the edges of the body is far from being as pro- 
nounced as in other cysticolous species. The cirri are small or 
wanting, except in the vicinity of the pharynx. On the ventral 
surface the small pointed parapodia are distinctly seen. I could 
find no indications of penes or suckers. 
The preservation of the specimens was so bad that I could do 
very little with the sections. 
Specimen No. 1, measured 0.75 mm. In it 1 could detect 
traces of the testes, but there were no ova in the body-cavity. 
Specimen No. 2, measured 1 mm. A few distinct but very 
young ova were found in the body-cavity; also a few masses of 
spermatogonia in karyokinesis. 
Specimen No. 3, measured 1.25 mm. There were a few 
young ova in the body-cavity, but no traces of testes could be 
found. 
All these specimens were evidently young and this is also in- 
dicated by the small size of the cysts and possibly also by the feeble 
reflection of the edges of the body. The intestinal ramifìcations were 
few in number. A pair of nepliridia could be traced out, as in all 
the other species which I bave examined. 
The meager and unsatisfactory data here recorded acquire sig- 
nificance only from a comparison with the next species to be de- 
scribed, M. pulmnar, I believe that the three specimens of il/, eremita 
which I have seen very probably represent three successive stages 
in the transition from the male to the female phase.
