and not projecting. The average height of an ossicle is 
about °6 millim. ‘The sutures are crenelate, showing that 
the articular surfaces must be striated. 
In No. 2 the stem is preserved to a length of 26 millim. 
and has a width of about 2°25 millim., and the ossicles have 
an average height of a little less than -4 millim. 
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 comes between B. ramosus and B. 
decadactylus, and this position is corroborated by the shape of 
the cup. On the other hand, the quinquelobate stem 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 genus the 
present species adds nothing. 
Note on Botryocrinus pinnulatus. 
My friend Mr. W. Madeley, of Dudley, wrote meas follows 
under date 27th Jan., 1892 :—“ I send you herewith a speci- 
men of (?) Botryocrinus, which I purchased from Mr. Gray’s 
collection. I think this 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. Crin., V.” (Ann. & Mag. Nat. Hist. ser. 6, 
vol. vil. p. 402). ‘The specimen, which consists of an almost 
complete crown and 45 millim, of stem, is tairly well preserved, 
especially in the lower part, and presents a few points of 
interest which may here be noted. 
Dorsal cup is shaped like that of the type specimen. Its 
height is estimated at about 8°5 millim.; the width below 
is 4 millim.; 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 appears to be smoothly concave, and the 
axial canal is not separate.
