134 The American Geologist. Septemhor, looo 
the most complete evidence that among the Poteriocrinidx, 
in many cases, the pores pass through the test." 
In support of tliis statement, we gave figures on Plate VII; 
viz., figs. 2, 5, 7, 8, 9 and lo. 
Commenting on the foregoing statement, and the figures 
of actual specimens given by us, Mr. Bather, in his review 
of our Monograph,* denies the accuracy of our figures, and 
expresses the opinion that the artist would not have drawn ■ 
figures 5 and 9 as they appear, if he had not been told to put 
in structures which he could not see. His commentary on this 
subject in full is as follows: 
"^'achsmuth and Sppinger now admit my statement for 
"Cyatliocrums, Eiispirqcrimis, and possibly the Cyathocrinidse 
generally, in which very likely the madreporite performed the 
functions of the tube-pores'; but they 'have the most com- 
plete evidence that among the Poteriocrinidae, in many cases, 
the pores pass through the test.' Perhaps they have. And 
yet I am still sceptical. It was examination of Scapliiocriints 
multiplex itself, the first and chief species in which such pores 
were observed, that made me doubt the observation. I have 
examined, with like result, specimens described and figured 
by Grenfell and by Loven. Now, let the impartial reader com- 
pare my detailed descriptions and the drawings by Liljevall, 
Hollick, and myself, magnified 8, 16 and 20 diameters, with the 
bald statements and drawings, scarcely more than natural 
size, published by Wachsmuth and Springer. He will admit 
that scepticism is justified.. Nay, more, let him examine 
two of the figures on which they specially rely, namely, pi. vii, 
figs. 5 and 9. He will observe that the supposed pores are 
drawn in the middle of each side of each hexagonal plate of 
the tube; each pore lies on a line passing between the centers 
of adjacent hexagonal plates. Then let him look at the . 
other figures, such as 2b, and he will note that the supposed 
pores are at the angles of the plates, and never on the radial 
lines. Let him then examine a few hundred specimens of fis- 
tulate genera, and he will find that the apparent 
pores or slits never are on the radial lines, but always at the 
angles or between the ridges of the folded plates. Some re-
