part of the intestine is the short and wide rectum. Thus the ali- 

 mentary canal apparently differs distinctly from that of Clark's 

 specimens, as there is no distinct stomach (cf. Apod. Holoth. Pl. V 

 fig. 13); but the examination of several more or less contracted 

 specimens, leads to the suggestion that Clark's statements are 

 due to contraction on the preservation of his specimens. The ali- 

 mentary canal is, in the specimens at 

 hand, for the anterior three fourth of its m 

 length fastened by the dorsal mesentery, 9 

 in the posterior end by the right ventral | 

 mesentery. 



The ciliated funnels are found in the I 

 mid-dorsal, the left dorsal and the right | 

 ventral interambulacrum. In the anterior I 

 end of body there is but one sort of ' 

 funnels, which are small and funnel-shaped, 

 and rather like the funnels on the mes- 

 enteries in the Micrournae. In the posterior 

 end of body there is besides the ment- 

 ioned small funnels, a second sort (Fig. 

 44. 8) which is much larger. These large 

 funnels may be ca. 1 mm long, and ar- 

 ranged with rather regular intervals, but 

 in some specimens they are a little wider 

 than the figure shows, and then they may 

 be rather crowded on the body-wall. The 

 shape of these wider funnels is not figured, 

 the two specimens in which they are found 

 being so contracted that the exact shape 

 of the funnels is not to be made out. 

 But in any case I have never seen any- 

 tning resembling the figure of the funnels given by Clark (cf. 

 Apod. Holoth. Pl. V fig. 12). The funnels drawn (Fig. 44. 8) are 

 from the noncontracted specimen figured (Fig. 43). The gonads are 

 large and branched several times, and the genital duct opens in 

 the dorsal interambulacrum a little behind the tentacles. A genital 

 papilla is wanting. 



In the posterior end of body there are, though with some
