Ammonites jubar, var. A. multiradiatus (R. Strachey MS.), 

 H. F. Blanford. 

 (H. F. Blanford, in J. W. Salter & H. F. Blaniord: Palseont. Niti, 1865, p. 82.) 



Professor Blanford states that " this differs from the normal form 

 in the greater number of its ribs (55), which are consequently more 

 close set and filiform. The variation probably occurs only in young 

 shells." In the Strachey Collection transferred from the Museum 

 of Practical Geology, and labelled with that Museum's label " Oolitic : 

 Niti Pass. Ammonites triplicatus (Sow.). Coll. by Col. Strachey," 

 there is a fairly complete specimen [C. 7366], 46*5 ram. in diameter, 

 which agrees very well with Blanford's description of this variety. 

 It has about 52 ribs in the outer whorl, and although labelled 

 * Ammonites triplicatus ' it certainly does not agree with that species. 

 This is the only specimen in the collection that corresponds to 

 Blanford's description, and it is therefore most probably the variety 

 referred to. 



12. Ammonites octagonus (R. Strachey MS.), H. F. Blanford. 



(R.F. Blanford, in J. W. Salter & H. F. Blanford: Palajont. Niti, 1865, p. 83, 

 pi. xii, figs. 2a, b.) 



According to Professor Blanford's description, " the only specimen 

 of this Ammonite in Colonel Strachey's Collection is a fragment, but 

 of larger dimensions and in better preservation than that previously 

 described from Spiti." This fragment is now in the British Museum 

 collection [C. 5032], having been transferred from the Museum of 

 Practical Geology, accompanied by one of that Museum's labels 

 on wliich was written in ink simply the name "Am. octagonus, 

 Strachey," without any record of either horizon or locality, and 

 without any indication that it was the figured specimen. But of 

 this fact there cannot be the slightest doubt ; fig. 2a representing 

 ^ lateral aspect of the fragment (reversed), and fig. 26 a much 

 restored transverse section of the whorl. 



Later in the same work (p. 106) Blanford united Strachey's 

 A. Hookeri with the present species under the name A. octagonus, 

 this species having been described some two years previously.^ 



13. Ammonites Hookeri (R. Strachey MS.), H. F. Blanford. 



(H. F. Blanford, in J. W. Salter & H. F. Blanford: Palfeont. Niti, 1865, p. 83, 

 pi. xvii, figs. \a-d.) 



The figures illustrating Professor Blanford's description (pi. xvii, 

 figs, la-d) have been drawn (reversed) from two specimens, which 

 are now in the British Museum collection [C. 5048 and C 5049]. 

 Fig. la has been drawn from the example bearing the register 

 number C 5048, and the other figures have been taken from the 

 specimen No. C. 5049. Both specimens were transferred, in 1880, 

 from the Museum of Practical Geology, the smaller one [C 5048] 

 labelled " Oolitic : Niti Pass. Ammonites Hookeri (Stra.). Coll. by 

 iOol. Strachey." There is now no Jermyn Street Museum label 

 with the larger specimen, but there is no doubt whatever as to its
