THREE NEW SPECIES OBSERVED IX THE YORKSHIRE LIAS. BY 
W. Y. VEITCH, ESQ. 
Whilst studying the Yorkshire Lias, collecting" and identifying" 
its fauna, several forms have been put aside for further and more 
careful consideration. Three of them have turned out to be species 
not previou.-^ly described : 
Chonetes Clevelandicus, P'igs. 1 and 2, is a brachiopod found 
attached to Waldheimia resupinata, and occurs in the main seam of 
ironstone in Ammonites spinatus zone at Eston. 3 examples. 
Fleuromya navicula, Fig. 3, is found in the Ammonites oxynotus 
zone, Robin Hood's Bay. Although several specimens have been 
secured in a frag'mentary condition from the shale Fig. 3 is the 
only perfect one I have been able to obtain, its preservation is due 
to its pyritous condition. 
Jsis llasica, Figs. 4 and 5. These figures are from fragments of 
a sclerobasic coral, and are of interest, because I can find no record 
of any such coral having been found in the Lias, it is of the tribe 
Isin;i3. I liave noticed it in the Ammonites capricornis and A. 
Janiisoni zones at Huntcliff and Rockcliff, and A. oxynotus zone, 
Kobin Hood's Bay. Fig. 4 was picked out of the shale of the last 
named zone, whilst Fig'. 5 is from a sandstone nodule in the first 
zone. It is common and gives the appearance of a robust horny based 
coral branching dichotomously, and is inclined to be arborescent, and 
must have been three or four feet in height. Sections of it under the 
one inch objective show a coarse cellular structure at the outer 
margin, tliis disappearing towards the centre where parallel striae 
become apparent, resembling the strife in horn.
