angular granules. The depressions iu the bases of which the calicles open are shallow. On 

 the stems, the ccenenchynia is much denser, and the pits wider and shallower, but very 

 uniform. 



There are four ramose specunens of this foveolate type, and two which appear to have 

 been broken off and to have continued to grow as free unattached colonies. This detached 

 method of life considerably alters the whole habit and aspect of the stock. But the evidence 

 wliich induces me to associate these two free stocks with the type is fairly conclusive. The 

 larger one is too large to roll about freely, and is, therefore, altered least j that it belongs to 

 this type, close comparison leaves but little doubt ; the smaller can be seen to be but an 

 advance on tlie last named, in that all the peculiar features of the large specimen which 

 differentiate it from the type are carried to an extreme, there being no resemblance to the 

 type left. But for the larger free stock, the smaller would have had to be classed by itself. 



The peculiar growth of the free stock is the same as that described for the detached 

 growths of M. multifornds (p. 63). They all show a tendency to send out processes radially 

 in all directions to form globular masses. If the detached mass is- heavy, see specimens d, e 

 of M. cnlicidata, these processes only radiate out from the npper and lateral surfaces, but if 

 small and light, they radiate out ia all dii'ections, the mass resting upon the tips of those 

 which happen to point downwards. These tips are generally somewhat swollen and rounded, 

 and consist of a rapidly growing reticular cojnenchyma.

Desm;ption. — CoraUum, forms variously shaped tufts, 10 to 11 cm. high, of ttiin. branches 

 5 to S' mm. thick, often flattened and expanding at their tips, fusing irregularly. Old stocks 

 which have been regrown over,, may form small massive clumps sending out irregular 

 branches. 



Calicles small, 0'4 mm., numerous, less than 1 mm. apart, conspicuous on the lower and 

 smoother portions of the stock, obscured by the crenenchyma on the upper and younger 

 portions. Aperture sharply circumscribed, being apparently cut out of solid coenenchyma.
