TYPE AMMONITES. 



We are glad to think that Mr. S. S. Buckman's enthusiasm 

 has resulted in part 24 of his ' Type Ammonites ' appearing ; 

 albeit the present pricesof printing, etc., are almost prohibitive, 

 as is nearly the price of part 24. We have struggled patiently 

 with his nomenclature, but regret to say we have had to give 

 it up, and in future before putting a name on to a fossil ammon- 



ite we shall submit it to Mr. Buckman or other specialist, and 

 probably find that the fossil is not an ammonite at all ! The 

 accompanying illustration of a Scarborough Kellaways Rock 

 Fossil we presume would once, in the ' good old days,' be called 

 Ammonites ordinarium. The label under it on plate 

 CLXXXIIL of the present publication gives ' Qticnstedticeras 

 ordinarium,' and ' Weissermeliceras longilohatum, S. Buckman 

 Callovian, athleta ; Genotype, Holotype, p. 20.' On the next 

 plate we have an illustration of Ammonites ingcns, from 

 Pickering. That is not so bad. But below is ' Dichotomoceras 

 ingens. Young & Bird, op. • argovian, Dichotomoceras ; see 

 CXXXIX,' and there are a lot of ' futurist ' zig-zags and 

 curves on the plate which do not simplify matters. Next we 

 get 'Ammonites poculum,' type spec, 'from near Gristhorpe.' 

 That we can manage, but as we read on it is ' Poculisphinctes
