Sheppard : Notes on Some Speeion-Clay Belemnites. 99 



the subject has enabled him to compare his specimens with those 

 found in the Neocomian strata on the continent — the result 

 being-, that with regard to the Speeton belemnites and their 

 nomenclature local geologists will have to begin de novo. 



In order however, to put the Speeton belemnites on a proper 

 footing, Mr. Danford's paper is accompanied by four beautiful 

 collotype plates, upon which twenty-six of the typical belemnites 

 — common and rare alike — are figured. Previously some of the 

 belemnites had not been figured at all. Others were in different 

 out-of-the-way publications which were difficult of access. The 

 Hull Society is certainly to be congratulated on enabling geolo- 

 gists for the first time to see the illustrations of the Speeton 

 belemnites together, and the plates are so well executed that 

 identification is quite an easy matter. 



The two plates accompanying these notes are from photo- 

 graphs of the specimens which Mr. Danford has placed in the 

 Hull Museum. The number of specimens figured in the memoir 

 under notice is much greater. The first plate (No. V.) shows 

 a number of deformed belemnites. Such examples are by no 

 means common. A deformed specimen from the chalk ot 

 Flamborough was figured in this magazine for May, 1904. In 

 one particular bed of the Speeton Clay, however (the ewaldi zom) 

 such abnormal specimens are not uncommon, that is to say, 

 to collectors of Mr. Danford's kind. .\s will be seen from the 

 photograph, some of the guards of these old time cuttlefishes 

 have evidently been damaged at an early stage in the life of the 

 animal. One or two look suspiciously as though some denizen 

 of the Neocomian Sea had taken a bite at these cuttlefishes, and 

 thus abnormally 'shaped their ends.' Others have similarly 

 suffered, either from damage or disease. The specimens 

 figured are : — i. B. puzosi. 2. B. ewaldi. 3. From the B. 

 lateralis beds. 4. P>om the B. bnuisvicensis beds, probably 

 B. speetonensis. 5. B. Jacnlum. 6. B. ? 7. B. miniums. 

 8. B. eimldi? Nos. 2, 3, 7, and 8 are probably post-mortem 

 deformities ; the remainder are obviously guards which have 

 been damaged and healed during the life of the animal. 



The other plate (No. VI.) illustrates some of the specimens 

 of more particular interest, described by Mr. Danford. The 

 species represented are, in order, i. (? New). 2. B. obtitsirostris. 

 3. B. bnuisvicensis. 4. B. Jasikowi. 5. B. speetonensis. 

 6. B. obsolutifoi'mis. 7. B, subquadratus.
