118 G. C. Crick — Strachei/s Cephalopoda from Himalaya. 



being the other specimen figured by Blanford. Each fossil has been 

 numbered in ink "1830"; this is Strachey's original number, and 

 indicates that the two examples came from the same locality, viz. 

 the Niti Pass, this being the only locality mentioned in the list of 

 fossils given on p. 102 of Salter & Blanford's work. 



The posterior third of the outer whorl of the smaller example 

 (fig. la) appears to be septate, whilst the rest seems to liave formed 

 part of the body-chamber. The larger example (figs. \h-d) is 

 entirely septate ; it is part of a whorl which must have been at least 

 70 mm. in diameter. The suture-liiie has been painted in, and 

 evidently formed the original of fig. \d. The transverse section 

 depicted in fig. Ic has been much restored. 



On p. 106 Professor Blanford places this species as a S3'nonym of 

 Strachey's A. octagonus, to which species he also refers Oppel's 

 A. Sommerringi} 



14. Ammonites medea. (R. Strachey MS.), H. F. Blanford.

 pi. xix, figs. 5«, b.) 



Professor Blanford says: "The only specimen of this MSS. 

 species of Colonel Strachey in his collection is tlie fragment figured, 

 from which it is difficult to pronounce upon its affinities. It may 

 be either, as surmised by Colonel Strachey, a species allied to 

 A. Jason, Zieten, or a portion of a large specimen of the tuberculate 

 form of A. WallicMi, Gray." 



This specimen is now in the British Museum collection [C. 5017], 

 having been transferred from the Museum of Practical Geology, in 

 1880, labelled with one of that Museum's labels "Oolitic : Niti Pass. 

 Ammonites medea. Coll. by Col. Strachey." It bears the number 

 "18" in white paint. It is not well represented in the figures: 

 the spines are not nearly so much elevated as shown in fig. 5b ; 

 and further, they are symmetrically disposed in regard to the median 

 line of the flattened (i.e. the peripheral) area, and not irregularly 

 placed as might be supposed from fig. 5a ; the two rows of spines 

 are 13 mm. apart, the spines being exactly opposite each other and 

 arranged in each row at intervals of about 5 mm. The fragment 

 shows no traces of septa, and appears to have formed part of the 

 body-chamber.
