Lyon and Casseday give the localities of this species as Clear Creek, Hardin County, 

 Kentucky, and Washington and Montgomery counties, Indiana. Lyon prepared excellent 

 figures which were never published, but were turned over to me when I acquired his collec- 

 tion. The type used for these figures is a weathered specimen in the very same preservation 

 as those from the Indian Creek bed, and beyond all question it came from that locality, as 

 there were also in Colonel Lyon's collection a number of other specimens from the same 

 place, and he is known to have collected there in early days. But there was in his collection 

 no specimen from any Kentucky locality labeled as, or which can be referred to, this species. 

 There was however a specimen of Onychocrinus ramulosus from Hardin County labeled 

 " Forbesiocrinus multibrachiatus," which probably accounts for the recording of that locality 

 in the description. 



The principal locality in Washington County, Indiana, has several species identical with 

 that of Indian Creek, and the horizons are probably closely equivalent. A few specimens 

 found in that vicinity may be referred to this species, among which is one figured on Plate 

 XXIX, figure 4, and the type of Miller and Gurley's F. speciosus {ibid., fig. 5). These 

 authors also referred the form chiefly occurring at Indian Creek to their F. washingtonensis, 

 distinguished by them from their earlier F. speciosus chiefly by the lack of anal plates in the 

 latter, which they figured and described as having the interbrachial areas all alike (16th 

 Report Geol. Surv. Indiana, p. 347, pi. 5, figs. 8, 9). On the type and only specimen (in the 

 collection of Mr. Gurley now in the University of Chicago, No. 6267) the sutures were 

 marked in ink as shown in their figures ; but this was careless work, as a little cleaning 

 showed the posterior basal truncate and having a large anal plate with others succeeding, 

 as appears by my figure 5 of Plate XXIX ; the arms are worn and flattened in the upper part, 

 but it is generally much like the present species. The single large anal plate interposed above 

 the basal is a variation occurring in some of these species which finally becomes constant in 

 the Warsaw. 



I have given two figures of Lyon's type, and it must be noted that it is flattened and 

 crushed so that the two posterior rays are pushed together, concealing most of the plates of 

 the anal side (PL XXVIII, fig. lb) ; in the anterior view the arms look flatter than in the 

 other specimens, but this is due to erosion. The specimen figured by Meek and Worthen, 

 Geol. Surv. Illinois, volume 5, plates 14, figure 2, and 15, figure 7, as Forbesiocrinus wortheni, 

 and now in my collection, is a much flattened and very mature example of this species from 

 the typical locality. 



The position of the small infrabas.il is somewhat irregular, being in a few specimens 

 anterior in position as in F. saffordi.

The specimens described under this name are from the Canton beds of 

 southern Indiana in Washington County, closely equivalent to those of Indian 

 Creek, and may be only another variety of F. zvortheni. They are somewhat
