66 G, C. Crick — Strachafs Cej^halopoda from llbnalaija. 



but from its lithological character there can be no doubt whatever 

 that it came from tlie Himalaya; it forms part of a nodule, like^so 

 many of the Niti fossils. It is 91 mm. in diameter. 



I have not been able to recognize in the collection the original 

 of Gray's pi. c, fig. 2, 



I have elsewhere expressed the opinion that the original of 

 Gray's fig. 1 was also the original of Blanford's pL xiv, figs, la, h^ 

 but this statement is incorrect, the original of Blanford's figures 

 beingin the Museum of the Geological Society of London (R. 10,116).^ 

 Blanford's figure is reversed. Both sides of the fossil are free from 

 matrix, and well preserved, the side opposite to that which is figured 

 being the better preserved of the two. On the figured side the 

 surface of the first third of the outer whorl has been injured just as 

 in the example figured by Gray ; this was evidently the septate 

 part; no septa are visible on the remaining two-thirds of the whorl, 

 which therefore most probably constituted the body-chamber. The 

 inner whorls, though incomplete, are better preserved than in Gray's 

 type-specimen. There is a slight iri'egularity in the ribbing of the 

 outer whorl, but not nearly so much as is indicated in the figure ; 

 on the side of the specimen opposite to that which is figured there 

 are 33 or 34 principal ribs in the outer whorl, nineteen of these 

 being in the last half-whorl. The measurements given by Professor 

 Blanford are as follows : — diameter, 4-8 inches [ = 122 mm.] ; 

 diameter [or height] of outer whorl, 2-2 inches [ = 56 mm.] ; 

 thickness, 1"9 inches [= 48'5mm.]. My own measurements of the 

 fossil are : — diameter, 121 mm. ; height of outer whorl, 55 mm. ; 

 height of outer whorl above preceding, 385 mm. ; thickness of outer 

 whorl, 48 mm. ; width of umbilicus, 29 mm.

The British Museum collection contains Gray's type-specimen 

 [No. C. 5051]. It is accompanied by a label belonging to the 

 Museum of Practical Geology bearing the following inscription : 

 "Oolitic; Niti Pass. Amruonites tenuistriatus. Coll. by Col. Strachey 

 (belongs to Brit. Mus.)," but the statement that it belonged to the 

 Strachey Collection is obviously incorrect, for, as we have already 

 stated in regard to A. Nepmilensh, Gray's figures were published 

 many years before Colonel Strachey's specimens were collected. 

 Although some of the matrix has been i-emoved since Gray's figure 

 was drawn, there are still indications on the fossil of the original 

 extent of the matrix, and there can be no doubt whatever about its 

 being the figured specimen. I have already shown elsewhere^ 

 that a portion of this specimen in its present condition formed the 

 original of Professor Blanford's pi. xv, figs. 26, c.
