NO. 3 ON THE FOSSIL CRINOID FAMILY CATILLOCRINIDAE 29 



undivided ; projecting unequally beyond the column, chiefly at the 

 right posterior side. The three smaller RR rectilinear, and not nar- 

 rowing upward ; the two large RR proportionally wider below and 

 narrower above than in typical Catillocrinus. Transverse outline of 

 cup elliptic. 



Dimensions : Long diameter 12 to 18 mm. ; height 4.9 to 6 ; number 

 of arms 13 to 23. 



Three species. All from a formation considered Permian by the 

 Dutch and German geologists. Island of Timor, Dutch East Indies. 



Paracatillocrinus granulatus Wanner 

 Diam. 13.5 mm.; height 4.9-5.5; arms 22-23. 



Paracatillocrinus spinosus Wanner 

 Diam. 18.8 mm. ; height 5.2 mm. ; arms 13. 



Paracatillocrinus ellipticus. Wanner 



Diam. 12.7 mm. ; height 6 mm. ; arms 14. 



All described in Professor Wanner's work above cited, pp. 10-15; 

 pi. XCVI, figs. 1-4. 



NEW SPECIES OE COLLATERAL GENERA 



As bearing on the geological range of Synhathocrinus in compari- 

 son with that of the Catillocrinidae, I have figured two new species 

 of that genus, and another of one closely related : 



Synbathocrinus hajniltonciisis n. sp. Pi. 5, figs. 13, 14 

 Differs from other species in the great depth to which the notch 

 for the reception of the anal plate is incised, and in the relatively large 

 size of the anal and succeeding plates. It is represented by a single 

 specimen from the Moscow shale of the Hamilton group. Middle 

 Devonian ; on Kashong Creek, near Bellona, New York. A small 

 species from the western Hamilton, 6^. inatutinus, was described 

 by Hall,* which has been recognized in Iowa and Michigan. It has 

 a much lower calyx than this. 



Synbathocrinus onondaga n. sp. PL 5, figs. 15, 16 



This is a small species of which the material is not sufficient for 

 close comparison, but its special interest lies in the fact that it is 

 the earliest known occurrence of the genus, being from the lower 

 member of the Middle Devonian, the Onondaga; below the hvdraulic
