192 Mr. F. A. Batlier on British Fossil Crinoids : 



and not projecting. The average height of an ossicle is 

 about '6 miilim. The sutures are crenelate, showing that 

 the articular surfaces must be striated. 



In No. 2 the stem is preserved to a length of 2(3 raillira. 

 and has a width of about 2*25 miilim,, and the ossicles have 

 an average height of a little less than -4 miilim. 



General Remarks. 



The relations of this species to the other described species 

 of the genus are pretty clear. The character of its arm- 

 branching shows that it conies between B. ramosus and B. 

 decadactjlus, and. this position is corroborated by the shape of 

 the cup. On the other hand, the quinquelobatestem reminds 

 us of the few stem-ossicles that are known of B. pinnulatus^ 

 and seems to show that too much stress may have been laid 

 on that character as indicative of advanced development. 



To our knowledge of the morphology of the geims the 

 present species adds nothing. 



Note 071 Botryocrinus pinnulatus. 



My friend Mr. W. Madeley, of Dudley, wrote me as follows 

 under date 27th Jan., 1892 : — "■ I send you herewith a speci- 

 men of (?) Botryoci-inusj which I purchased from Mr. Gray's 

 collection. I think tliis is from the Upper or Thin Lime- 

 stone at Tividale, Dudley." 



The specimen in question turns out to be an example of 

 Botryocrinus pinnulatus, one of the species described in 

 <' Brit. Foss. Grin., V." (Ann. & Mag. Nat. Hist. ser. 6, 

 vol. vii. p. 402). The specimen, which consists of an almost 

 complete crown and 4o miilim. of stem, is fairly well preserved, 

 especially in the lower part, and presents a few points of 

 interest which may here be noted. 



Vorscd cup is siiaped like that of the type specimen. Its 

 height is estimated at about 8*5 miilim. ; the width below 

 js 4 miilim. ; the width above cannot well be estimated, as 

 the cup is much flattened and the plates disarranged. 



The following are the measurements of the various plates : — 



The radial facet ajipears to be smoothly concave, and the 

 axial canal is not separate.
