4) On the former occasion, the paper of C. ReiiD with the important contribution on the 

 Ordovician and Gotlandian fossils of central Himalayas (Palaeontologia Indica, Ser. XV., 

 vol. VII., No. 2. 1912) escaped my attention to my great regret. That paper includes his 

 descriptions of two new forms of Halysites from th; Gotlandian roXks Hor. 5. from 

 Kanaur, Bashahr and Spiti, which are: 



Ha'ysites catemdaria var. kaiiaitremis Reed 

 H. ivallkhi Reed. 



The fo:mer shows a corallum composed of stout flexuous laminae, markedly constricted 

 between the succesMve corallites; the corallites are subcircular or subelliptical, and occa- 

 sionally intercalated with interstiiial tubes. Spines are not present in this form. 



The second species, on the other hand, is characterized by its slender corallum, the 

 chain of which forms a loose and open network ; the corallites are subquadrate in 

 cross section, broadly united end to end; there are neither interstitial tubes nor septal 

 spines. This new species is, in my opinion, hardly distinguishable from H.parallelia 

 from Gotland.
