562 MISS JANE DONALD ON THE OENEEA [Nov. I906, 



Lophospika Sedgwickii, sp. UOV. (PI. XLIII, figs. 11 & 12.) 



Diagnosis. — Shell of medium size, turreted, composed of about 

 seven whorls. Whorls angular, increasing at a moderate rate, flat 

 or slightly concave above the angle, flat below, base convex. A 

 prominent flange-like keel, which represents the sinual band, is 

 situated on the angle above the middle of the body- whorl and is sub- 

 median on the whorls of the spire. Ornamentation consisting of a 

 strong keel a short distance below the band and a very fine thread 

 immediately below the upper suture. No lines of growth discernible. 

 Aperture longer than wide, lip reflected on the columella. Umbilicus 

 small. 



Remarks and Resemblances. — In the Sedgwick Museum 

 there are two external moulds from the Mullock-Hill Sandstone, 



marked ' M. joulchra, M'Coy (414),' which are quite distinct from the 

 Irish type of the species, both in form and ornamentation. They 

 more nearly resemble L. gyrogonia, M'Coy, in having a prominent 

 flange-like sinual band and a keel a short distance below, but may 

 be distinguished by the smaller spiral angle, minute umbilicus, less 

 oblique sutures, and less exsert whorls, which show no tendency 

 for the body-whorl to become detached. They are also somewhat 

 like L. 'perangulata, Hall, but neither these two specimens, nor six 

 others in Mrs. Gray's collection from the same locality, are suffi- 

 ciently well-preserved to admit of an accurate comparison being 

 made. 



Dimensions. — The largest specimen (PL XLIII, fig. 12) in 

 the Sedgwick Museum consists of about six whorls ; its length 

 = 13 millimetres, and the width of the penultimate whorl = 7 mm. 

 That figured in PI. XLIII, fig. 11, belonging to Mrs. Gray, consists 

 of six whorls in a length of 12 mm. ; its width = 8 mm. Both 

 the above are external moulds. Another specimen of Mrs. Gray's 

 is partly an internal and partly an external mould; it consists of 

 about seven whorls in a length of 13 mm. ; width of penultimate 

 whorl = 6'5 mm. 



Locality and Horizon. — Mullock Hill (Ayrshire), in beds of 

 Lower Llandovery age [Lap worth].

Lophospika fekkuginea, sp. nov. (PI. XLIY, figs. 1 & 1 a.) 



Diagnosis. — Shell turreted, moderately elongated, consisting of 

 about ten whorls. Whorls broad, angular, concave above and 

 flattened below the angle. A prominent obtuse keel is situated on 

 the angle, which is near the middle of the body- whorl and below 

 the middle of the whorls of the spire. This keel is bordered on 

 each side by a fine line, and that it represents the sinus in the outer 

 lip is shown by the lines of growth curving back to it above and
