138 DEIMATIDAE. 



usually have 4 rays or arms (Plate 4, fig. 7) but often there are 5 or more (Plate 4, 

 fig. 8); the arms are flat, perforated with several holes at their enlarged tips, 

 and occasionally have little spines on the sides. The whole spicule is rarely 

 200 ix long, while somewhat similar spicules in S. protedum are about 700 fi long.

One specimen. 



This species is readily distinguished from other known species of the genus 

 by the very small and characteristic spicules. It is unfortunate that the con- 

 dition of the specimen does not permit a better knowledge of its external features 

 and internal anatomy. 



Scotodeima setigerum. 

 Ludwiq, 1893. Bull. M. C. Z., 24, p. 109. 



Although these specimens are in fairly good condition, they contribute 

 nothing of importance to Ludwig's full account (1894, Mem. M. C. Z., 17, p. 

 74-79). They range in length from 55 to 88 mm.

Laetmophasma fecundum. 

 Ltowig, 1893. Bull. M. C. Z., 24, p. 109. 



The specimen, about 50 mm. long, is in such wretched condition that there 

 is little certainty about the identification. But there is no doubt that some 

 at least, of the now more or less decalcified, deposits were wheels like those 

 of L. fecundum and there is nothing improbable about the specimen represent- 

 ing that species.

Capheira sulcata. 

 Lotwig, 1893. Bull. M. C. Z., 24, p. 109. 



The representatives of this species are in very bad condition indeed but 

 the calcareous particles agree well with Ludwig's description and figures (1894,
