propriety, be regarded as a decorated form of L. staphyllearia. 

 Locality : It occurs at seventeen localities, chiefly Nos. 1, 3, 9, 17, 

 18, 29, 32. PI. 17, fig. 16 is drawn from the largest specimen.

The test is compressed, carinate and apiculate. The curved 

 bands on both faces are extremely fine and perhaps just raised 

 above the surface. There seems to be no reason why it should 

 not be brought under the above heading, although in the Delos 

 examples the curved bands are broad and scooped out, the test. 

 little compressed, the keel not so prominent, and the apiculate 

 process not present. It occurs at many stations. Locality ;. 

 Chiefly Nos. 18, 19.

Both the carinate and non-carinate forms are present, but the 

 carinate is far more frequent. Sometimes there are only a couple 

 of spines connected by a small keel, at others simply a keel, 

 which is dentate. 



PI. 17, fig. 19. This form varies little, and occurs only at 

 a few stations. Locality : Chiefly at Nos. 9, 11, where it is 

 common. 



PI. 17, fig. 20 has the orifice to one side and is hooded. The 

 tube is attached to the back of the test. Locality : Various 

 stations, chiefly at No. 32. Always rare. 



PI. 17, fig. 21. In this variety the keel is carried right up to 

 the orifice, which is a narrow^ oval. In some of the specimens the 

 two side spines are not placed quite so high up as in the one 

 selected for illustration. The orifice is fissurine. This form 

 appears to be closely allied to Fissuri7ia tricuspidata Reuss, 

 1870, p. 470; von Schlicht, 1870, pi. 5, figs. lQ-\^. Locality : 

 Nos. 3, 6, 7, 24. Always very rare. 



PI. 17, figs. 22, 23. These are very small, and may perhaps 

 be a weak form of the compressed variety named by Brady 

 L. longispina in the Challe7iger Report. I cannot, however, see
