‘that time the term Clonograptus had not been generally applied 
to the group of graptolites which bear it, otherwise we may sur- 
mise that Linnarsson would have used it. lLinnarsson’s ex- 
amples, as he himself, says were imperfect. His diagnosis is: 
“ Rami tenuissimi, regulariter dichotomi, circiter } mm. late. In 
10 mm. 7-8 cellule anguste, elongate, subrect, apertura run- 
cata, transversa.” In its slender branches and distant hydro- 
theca it differs from the type of the genus occurring in the 
Quebec Group,and is small and slender like the St. John 
Species. 
Since Linnarsson first described the specics, Dr. J. C. Moberg 
has added largely to our knowledge of it by describing a num- 
ber of examples from Hunneberg, found in the collections of the 
Geological Survey of Sweden.* These are more complete than 
those described by Linnarsson, and give a better conception of 
the species and of its generic place. The examples figured by 
Moberg show the species complete from the sicula to the ex- 
tremities of the branches, and also show that the species did uot 
reach the fifth order of branching as did C. proximatus. + The 
most obvious point of difference, however, is the long funacle 
and primary and secondary branches, through which a more 
open form is given to Linnarsson’s species than to C. proximaius. 
Size of C. proximatus. Diameter of the hydrosome 25 mm., 
width of the twigs about 4 mm. 
Horizon and Locality. In the black, carbonaceous shales of 
Band ¢ of Division 3 of the St. John Group, at Navy Island in 
St. John Harbor. Scarce. Collected by G. van Ingen. 
The close association of this and the species described below 
with D. flabelliforme makes a comparison of the geological 
horizon of our species with that of C. fenellus of interest. Lin- 
narsson has stated distinctly that the latter is found together 
with Spherophthalmus alatus Boeck, and thus belongs to the 
highest layers [of the alum slate or Olenus Zone]. This refer- 
ence is called in question by Dr. Moberg, who gives various 
reasons for claiminig this graptolite as belonging above the 
Dictyonema Zone. 
Among other things he says that in all the literature hereto- 
fore given relative to the geological age of the shale in which 
Clonograptus tenellus Linrs. is contained at Hunneberg, the age 
given rests upon the statement left by Linnarsson, who first dis- 
tinguished that layer. This statement I have given above, and

+ Moberg’s description speaks of the fifth order, but this is because he counts the 
funicle as the first branch. As we have found no theca on the funicle of C. proximatus, 
we do not regard it as a branch, but continue Hall's use of the term funacle.
