Holotype. — 'Sjn. Char. Carb. Foss. Irel.' pi. iii, fig. 1. Grriffith

 of the Carboniferous Limestone.

 high in the Lower Carboniferous Series. 



AcLisiJS'A SUBELOXGATA, sp. noy. (PL YI, fig. 1.) 



Diagnosis. — Shell elongated, turriculated, composed of more 

 than ten whorls. Whorls angular, flattened aboye, slightly conyex 

 below. Ornamentation consisting of a strong thread on the angle 

 ^yith one aboye and three belo"\y, space immediately above the angle 

 rather wdder than those below, four or fiye additional yery fine 

 threads on the base. Aperture not well preserved. Columella 

 nearty straight. Sutures deep. 



Remarks. — This species greatly resembles A. elongata (Flem- 

 ing), but the spiral angle is rather wdder, the wdiorls are more 

 angular, and the threads ornamenting the spire fewer and coarser. 



Holotype. — PI. VI, fig. 1. Though small this specimen is 

 almost entire. Length=4-25 millimetres ; wddth=l-25 mm. In 

 Mr. John Smith's collection. 



Locality and horizon. — Moss Mullock, Kilwinning, in the 

 Upper Limestone Series. 



There is another example from this localit}^ in the same collec- 

 tion, as w^ell as one from Glencart, Dairy, also in the Upper 

 Limestone Series. The Young Collection, Kelyingrove Museum, 

 Grlasgow, contains two specimens from Grlencart, one of which is 

 bigger, haying nine whorls in a length of 8 mm. ; both apex and 

 base are bi'oken. A shell in the Museum of Practical Geology, 

 London, appears to belong to this species ; it is, hoAvever, much 

 larger and is somewhat crushed. The exact localit}^ is not stated, 

 onh^ ' Glasgow^ ' being given. It has the appearance of specimens 

 derived from the Lower Limestone Series, wdiere they frequently 

 attain a greater size than those from the L^jDper Limestone Series. 

 Its length = 14 millimetres for seven whorls, the greatest width of 

 which = 5 '5 mm.
