Lagena striata (d'Orbigny), plate XIV. fig. 16. Oolina striata 

 d'Orbigny, 1839, Voy. Anier. Merid., p. 21, plate v. fig. 12.— This 

 beautiful form has a somewhat egg-shaped chamber, delicately 

 ribbed, and a long neck ornamented with very thin rings of 

 shelly matter, at regular intervals. Our specimen differs from that 

 figured in the ' Challenger ' Monograph, plate Hi. fig. 22, in that 

 the neck-rings are oblique in that specimen, whilst in ours they 

 are horizontal. One specimen ; brown clay. 



Lagena striata (d'Orbigny), var., plate XIV. fig. 17. — Most 

 likely a variety of the last. D'Orbigny 's original figure is round, 

 with a flattened base, like an onion, and therefore this is more like 

 the type. It has evidently lost its neck ; and at the base there is 

 a small projection. One specimen ; brown clay. 



Lagena sulcata Walker and Jacob, plate XIV. fig. 18. Serpula 

 {Lagena) striata, sulcata, subrotundata, Walker and Jacob, 1784, 

 Test. Min., p. 2, plate 1, fig. 6. — A coarsely ribbed ovate test. 

 Unfortunately, only half of this specimen remains. It has split 

 longitudinally, but its characters are so well marked as to make it 

 easy of identification. One specimen ; brown clay. 



Lagena (Obliquina Seguenza) oviformis n. sp., plate XIV. 

 fig. 19a— cZ. — Test thick, symmetrically oval, perfectly smooth, and 

 glossy ; orifice lateral, large, at the top of a short truncated cone, 

 in the second sixth of the side. The aperture is round or semi- 

 circular. When round it has a notch in its upper lip reaching to the 

 base of the cone. This form appears to be entirely new, the nearest 

 to it being Seguenza's Obliquina acuticosta, figured in Terr. terz. 

 Messina, 4to, Messina, 1862, p. 75, plate ii. figs. 65-67. We do not 

 consider the lateral aperture of " generic " value, and therefore keep 

 to Lagena. Amongst other figured Lagenidse as approximating to 

 this variety may be mentioned a broken and repaired specimen 

 of L. vulgaris Will., figured by 0. Kymer Jones, Trans. Linn. Soc, 

 xxx., plate xix. fig. 2, and Lagena apiculata Keuss, Brady's 

 ' Challenger ' Monograph, plate lvi. fig. 4. In both of these the 

 aperture is lateral. G umbel's L. perovalis, figured in ' N. Alp. 

 Eocangebirge,' Abh. K. Bayer. Ak. Wiss., 1866, Bd. x., plate i. 

 fig. 7, is closely similar in outline. The little notch in the upper 

 lip might have been regarded as of more value, were there not one 

 specimen at least without it. Five specimens ; black clay.
