The calcareous deposits from the two ends of body are not 

 distinctly different. The anchors (Fig. 25. 2) measure ca. 180 fi in 

 length and 100 \i in width. The stock is finely dented and on the 

 vertex there are minute knobs. The anchor-plates (Fig. 25. 3) 

 measure ca. 150 in length and 125 fi in width. The articular 

 hole is smooth and on the bridge there are some few teeth. In 

 the posterior end of the plates there are three small holes. The 

 miliary granules (Fig. 25. 4) are rosettes of irregular size and 

 shape. 



I quite agree with Clark that "young individuals (and perhaps 

 adults) of two or more species are confused under the name 

 reticulata''. As seen above Sluiter's variety maculata may be 

 regarded as a valid species, and the following species lamperti, 

 most likely agrees with Lampert's striped specimens of "reticulata" .

The specimen at hand measures 5 cm in length by 0,3 cm in 

 diameter. The colour is grey with five purple stripes, one in each 

 ambulacrum. It has 10 tentacles each with ca. 15 pairs of digits, 

 united by a web. Eye-spots are present on the oral disk. The 

 calcareous ring is pure white and in shape quite as the ring of 

 reticulata. The cartilaginous ring is well developed and there are 

 no "tentacle-canals", but only large holes through the posterior 

 margin. There are 10 polian vesicles and a single stone-canal. The 

 gonads are branched and the loop on the intestine is wanting. The 

 alimentary canal is in its whole length fastened by the mid-dorsal 

 mesentery. The left dorsal mesentery is very large, as in the 

 specimen of hydriformis, which is lacking the loop on the intestine, 

 but not united with the intestine. The right ventral mesentery is 

 very faintly developed, and only fastened to the rectum. On the 

 two large mesenteries there are a great abundance of ciliated 

 funnels. 



The anchors (Fig. 25. 7) measure ca. 230 /< in length and ca. 

 150 ^ in width. The stock is finely dented, and on the vertex
