248 STATHEK : BELEMNITES OF THE YORKSHIRE CHALK. 
estimated the extra depth of Chalk inland. In addition, I have 
been fortunate in obtaining a number of Belemnites from beds 
in Avhich previous workers had not been successful in obtaining 
specimens, so that we are in a position to record a much more 
complete series than was hitherto possible. 
Presumably basing his opinion on the specimens he collected, 
Dr. Rowe suggested that the highest beds of the Yorkshire Chalk 
occurred in the A\ell-known pit at Ruston Parva \v'hich yielded the 
most deeply alveolated specimens he obtained. On purely strati- 
graphical grounds I Avas led to doubt this, but, fortunately, the 
finding of specimens in the White Hill Pit on the Scarborough 
Road, a mile north of Bridlington Old Town, confirmed my sup- 
positions. The specimens which I obtained myself, as well as 
others since found by other A\'orkers, unquestionably have a much 
deeper alveolus than any hitherto recorded for the Yorkshire 
Chalk, and on my submitting these specimens both to Dr. Crick 
and Mr. C. Da vies Sherborn. it was stated by both that unquestion- 
ably the examples were Act. quadratus, and Mere therefore new- 
records for the Yorkshire Chalk. 
In his paper. Dr. Rowe states he was not successful in finding 
any remains of Belemnites in lower beds than the flintless Chalk 
south-west of High Stacks ; consequently he was not able to 
produce an}' form attributable to westpJialicus. A careful 
examination of the upjDer flinty beds north of High Stacks has 
recently resulted in at least two Belemnites being found. These 
unquestionably have the characters of westphalicas , and were much 
shallower in the alveolar cavity than any previous Yorkshire 
examples. They occurred well within the flint beds, and if 
ivestphnlicns occurs in Yorkshire at all, these specimens may 
safely be said to be of that species. 
In endeavouring to ascertain the exact stratigraphical 
position of the species figured by Dr. Rowe^ some little difficulty is 
experienced by an amateur from the fact that he locates his various 
specimens from such and such a zone, Avhereas it is not always 
readily ascertainable what precise position in the Chalk these 
zones occupy. In working out the details of these Belemnites, 
I have felt that it would add value to the observations if the 
precise relative position of each specimen should be obtained, 
and by taking the first line of flint nodules at High Stacks as a
