small, as shown in text-fig. 93, fig. 6, p. 369, which is drawn 

 from the left-hand middle specimen. The large monaxons 

 are often short and stumpy, especially in the right-hand 

 middle specimen, which is further unique, in my ex- 

 perience, in that the unpaired rays of some of the 

 trii-adiates are shorter than the paired rays. In general, 

 these young specimens do not show the characteristic 

 elongation of the impaired ray so markedly as the larger 

 specimens examined by me. 



4. Bowerbank Coll., No. 987. Labelled, in Ridley's hand- 



writing, " Grantia hotryoides. North Harbour, Peterhead 

 Beach. No. 4, 1851. J. S. Bowerbank." A somewhat 

 abnormal specimen of L. comjilicata (see text-fig. 92, 

 figg. 4 a-ij, p. 367). 



5. Bowerbank Coll., No. 986. Bowerbank's label, copied by 



Ridley, is as follows — " Grantia hotryoides John. Guern- 

 sey. Mr. Buckland."

 River. 



8. Register No. 95.4.6.1 . Labelled " Leucosolenia hotryoides " 



in Bowerbank's handwriting and "type sp." in Carter's 

 handwriting, meaning apparently Bowerbank's type (see 

 text-fig. 93, figg. 7 a-7 j, p. 369). 



9. Register No. 95.4.6.2. Labelled exactly as the last (see

10. Register No. 85.1.9.32-34. Labelled " Calcarea, about 



15 fathoms off" Port St. Mary, I. of Man. J. Lomas, Esq." 

 Rather an abnormal specimen of complicata (see text-

* In the Catalogue of the Calcarea of the Berlin Museum, published by Breit- 

 fuss [31, this specimen, No 1780, and others are put down with the labels copied from 

 the bottles, without, apparent!}', any attempt at verification. The author is evidently 

 unacquainted with Ascandra {Clatlirina) contorta, otherwise a glance at the 

 specimen would have prevented his making this error : but it is surprising that he 

 did not examine the spiculation.
