Tryplasma Lonsdalei, car. minor, var. non. 
(Plate XYI, Figs. 3 and 4; PI. XXIV, Fig. 9; PI. XXV, Figs. 6 and 7 ; PI. XXVT, Fig. 11.) 
Observations. — The principal varietal character of this coral is in a 
diametrically opposite direction to that of the var. sc alar if or mis — the corallites 
are smaller than those of T. Lonsdalei proper. 
The corallum is formed of fasciculate masses of considerable size, 
closely imitating in its growth that of fasciculate species of Lithostrotion and 
Eiphyphyllum. The corallites do not exceed live millimetres in diameter, and 
vary between that measurement and four millimetres. The septal laminae 
agree in number with those of the species in chief, but the spines are 
proportionately longer. There appears to he a complete absence of groups 
of close tabulae, although the floors coincide in their distance apart with those 
of T. Lonsdalei proper. In general terms, its structure may he said to be 
that of the latter, hut the corallites are of a decidedly smaller habit, and in 
consequence the colonies at once attract the eye of the collector in the field. 
This variety is also more truly fasciculate than the species in chief, 
and the corallites are clustered much closer together ; in fact, in a large 
number of instances, they are actually united laterally. The fistuloe are also 
well developed, and form a prominent feature in weathered specimens (Plate 
XXVI, fig. 11).
