rapidly. It probably was short and did not serve as a means of 
attachment in mature specimens. 
In the Walker Museum of Chicago University there are three 
specimens of Lepadocystis moorei belonging to the Faber Collection, 
and numbered 9961. 
Of these, one specimen. A, is defective at the base, but otherwise 
is remarkably well preserved (plate V, Fig. lA, C), The orna- 
mentation is of the parallel line character, as in the type, but cer- 
tain of the lines are slightly stronger, and it is evident that by 
the accentuation of the stronger lines the stellate ornamentation 
of the smaller specimens could be derived. Of the first row of 
plates, only plate 1 is preserved entire. The basal parts of 
plates 7 and 8 are missing. The ambulacrum, which crosses the

left side of plate 19, slightly overlaps the adjacent edge of plate 
13 and intrudes upon the upper left hand corner of plate 14, at 
the left of the pectinirhomb 14-15. All of the ambulacra are 
remarkable for their length. That on plate 16 reaches the extreme 
lower angle of the plate. That on 17, borders the upper right hand 
side of the pectinirhomb and does not quite reach the lower angle. 
That on plate 18 terminates in a similar position. That on 15 
overlaps the tips of the adjacent angles of pectinirhombs 14-15 
and 10-15. Only the lower outlines of plates 20, 21, 22, and part 
of 23 are faintly perceptible.
