work of rapidly budding corallites ; the irregularity of growth is caused 

 by the constant twisting of the corallites, and the giving off of many 

 young corallites at different angles. One specimen in the collection 

 shows a basal reticulation, about three by two inches across, adherent 

 to the upper surface of a Favosite.

A specimen of Syringopora, referable to this species, was collected by 

 Dr. A. R. C. Selwyn, at Fossil Point, on the Peace River, B.C. The 

 corallites are slightly flexuous, about % of a line (1*7 mm.) in average 

 diameter, and distant from J line to 1 line from each other ; they are 

 connected together by numerous moderately slender transverse tubes 

 from 1 to 2 or 3 lines apart. In longitudinal and transverse sections 

 the usual invaginated plate structure is seen. 



The specimen of S. reticulata figured by Goldfuss is from Olne, in the 

 province of Limbourg (lower Carboniferous) and Nicholson regards this 

 species as one of the most characteristic fossils of the Carboniferous lime- 

 stone of England. The rocks occurring at Fossil Point have been re- 

 ferred by Mr. Whiteaves (op. cit.) to the Devonian or Carboniferous 

 formations.*

In the collection of this survey, is a specimen of Syringopora which 

 appears to agree better with this species than with any other. Its coral- 

 lites average in diameter about 1J line j they are slightly flexuous, often
