wanting. The "bridges" across the side-holes are often perforated. 

 The miliary granules (Fig. 40. 9) are either C-shaped bodies or 

 oval rings. In some specimens nearly all the granules are rings 

 and in others the majority are C-shaped. In most of the specimens 

 there are more rings than C-shaped bodies. The miliary granules 

 are found in the ambulacra, where they are often lying in rows. 

 They are not different in the two ends of the body. Besides 

 in the ambulacra miliary granules are also found in the small, 

 white papillae which are found all over the body. There are usually 

 2 — 8 granules in each papilla (Fig. 40. 1 1). The rods in the digits 

 are of the same shape as those in the tentacle-stem. They are 

 rather short and thick and their ends are enlarged and perforated 

 (Fig. 40. 10). 



This species is characterized by the shape of the calcareous ring, 

 the anchors and anchor-plates, and the ciliated funnels, and in having 

 the genital papilla between the dorsal tentacles. It is closely related 

 only to roseola (Verrill), from which species it differs distinctly in 

 the shape of the ciliated funnels, the size and shape of the anchors 

 and anchor-plates, and in the arrangement of the genital papilla.

The name Leptosynapta roseola was proposed by Verrill for 

 the little red Synaptid, found at the Atlantic coast of the United 



!) Of the 79 specimens from Bermuda at hand, the 52 are distinctly red 

 and the 27 pure white. Besides the 79 complete specimens there are 

 many fragments, which are all either pure white or distinctly red, and 

 for that reason easily separated into the two groups, the typical roseola 

 and the variety alba.
