casts) ; Cyprimeria (Cyclorisma) resembling rotomagensis dOrbiguy (6 speci- 

 mens) ; Pecfen (Camptonectes) ciirvatus Geinitz (3 specimens, small): Lima 

 {Mantellutyi} resembling- gaidtina Woods (2 specimens) : Liryia (Plagiostoma) 

 globosa J. de C. Sowerbr (mentioned in our previous list as ' resembling ' this 

 species ; identification now confirmed on the strength of several specimens) ; 

 Pteria {Ojcytoma) pectinata (Sowerbj) (many specimens: probably =:'Avicula 

 sp. indet.' of our previous list) : also (genus only) Limatula and Xucvla. 



Echinodermata. — The fossils of this Class in the collection at Cambridge 

 have been recently examined by Prof. H. L. Hawkins, who has published two 

 notes on the subject rathe Geological Magazine. Feb. it Sept. 1921 (pp. 57-60 

 & 420-26). The following are his identifications : he says. ' Unfortunately^ 

 most of the Echinoids are very indifferently preserved, so that specific deter- 

 mination is often doubtful, and in some cases impossible.' 



Cafop'jgus columhari^'s AgB-Ssiz (2 specimens); yucleoJites lacnnosiis Gold- 

 fuss (1 specimen) ; Pyrina aff. leevis Agassiz (4 specimens) (all in our previous 

 list). Cardiaster flatis^imus Agassiz (definitely so named in our previous 

 list). Eadioles of Cidaris hoicerhaiiki Forbes. 



The above are species previously recorded ; the following are additions to 

 our list : — ' Pyrina ' sp. nor. (? nor. gen.) (1 specimen) : subsequently 

 described and figured as Conidopyrina anomala Hawkins. Pyrina cf. 

 inf.ata d'Orbigny (1 specimen); P. cf. desmoidinsi d'Archiac (2 specimens); 

 Pyrina sp. (or spp.) (2 specimens): ' Echinospatagus' aff. murchisoniaiuis 

 (Mantell) (1 specimen). Cardiaster cf. fossarins (Benett) (2 specimens). 

 Internal moulds of — ? Peltastes or ? Salenia (1 specimen): fPseudodiadema 

 or ? Diplopodia (1 specimen) ; and ? Cardiaster or Holaster (2 specimens). 



Prof. Hawkins remarks : — ' All the specimens of Pyrina are probably 

 shape -variants of a single species ; the forms attributed to P. Isevis being 

 immature.' . . . ' The outstanding feature is the relative abundance of Pyrina^ 

 about half of the specimens being referable to that group. This probably 

 indicates littoral conditions ' {op. prius cit. p. 59 ). 



I shall have occasion to comment on this list in the concluding part of my 

 paper (pp. 76-77). 



Crustacea. — The collection at Cambridge contains several casts of the 

 carapace recognized by Mr. H. Woods as Cyphonotus incertus Bell. An 

 example of the same form, named by ^Ir. E. T. Newton, is among the fossils 

 of my own collection at Jermyn Street. 



Polyzoa. — Among the fossils at Cambridge are a few polyzoa, to some of 

 which the following provisional names have been attached : — Reptomultisparsa 

 cf. rnegalopora (Tine) ; Heteropora sp. : and Trernacystia sp. 



Crinoidea. — The fossils mentioned in L.W.. p. 244, as •joints of a large 

 round- stemmed crinoid. recalling . . . BoxirgueticHnv.s . . .' have been examined 

 by Dr. F. A. Bather and identified as Torynocrinus, a genus beginning in the 

 Lower Cretaceous and not known abore the Red Chalk ; the Shenley form is 

 not referable to the species found in the Eed Chalk of Hunstanton. Besides 

 those in my own collection, there are several specimens at Cambridge. 



Fossils of the Gieeiisaiid and Breccia associated with tlie 

 Shenley Limestone. 



Excepting the traces of shells in the decomposed calcareous 

 patches, mentioned on pp. IS & 20, the iron grit-breccia and its 

 accompanYing gritty loam and sand are almost devoid of fossils, 

 the only examples that I have fomid being a specimen of •' Janira 

 quinquecostata ' and an imperfect ' Pecten " in glanconitic loam at 

 Miletree Farm pit (fig. 11, p. 20) ; a small round palatal fish-tooth, 

 and a Tvorn fragment of the vrhorl of a phosphatized ammonite, 

 probably a pebble like that referred to on p. 17, at Xine Acre pit 

 (fig. 7, p. 16) ; and two or three worn casts of • Terebratula ' at
