ca. 180 /a in length and 110 ^ in width. The stock is finely dented 

 and on the vertex there are minute knobs. The anchor-plates from 

 the anterior end of body (Fig. 22. 17) are nearly oval and measure 

 ca. 1 10 jt* in length and 90 /a in width. In the posterior end of body 

 the anchor-plates are nearly all more or less reduced (Fig. 12. 14 & 16). 

 Those which are not reduced (Fig. 22. 15) measure ca. 110 ^ in 

 length and 100 fi in width. The articular hole and the bridge is 

 usually smooth, and in the posterior end of the plates there are 

 three small holes. The miliary granules (Fig. 22. 1 1) are in spite 

 of the small size of the specimen and the anchors and anchor-plates 

 unusually large. They are ca. 30 fi large circles of minute granules. 

 Whether they have really been rosettes in the living specimen or 

 not, it is not possible to see, but there is nothing to indicate a 

 partly dissolution, 



5. neirensis is not closely related to any of the other species of 

 the genus, and it is easily recognized by the shape of the calca- 

 reous deposits. 



Synaptula madvepovica n. sp. 



Zamboanga. 2. III. 1914. 6 specimens. 



The specimens at hand are varying in size, the largest measuring 

 31 cm in length and 0,5 cm in diameter. The colour is uniformly 

 dark grey and the dorsal side is a little darker than the ventral 

 side. There are 13 tentacles, which in all the specimens are stretched 

 straight out in the prolongation of the body. The tentacles measure 

 in the largest specimen 1,5 cm in length, and are for ca. 2 mm 

 united. Each tentacle has ca. 20 pairs of very contracted digits, 

 which are united by a web. The eyes are very small and not visible 

 on the oral disk. The calcareous ring (Fig. 24. 3) is pure white and 

 nearly quite buried in the large cartilaginous ring. On the exterior 

 side of the calcareous ring there are distinct muscular impressions, 

 and the radiais are perforated for the nerves. The cartilaginous ring 

 is as in psara large and with 13 small perforations close to the 

 posterior margin. There are many polian vesicles and a single stone- 

 canal. This is in the mature specimens very peculiarly formed, as 

 the basal part of it is curled up into a large clue, which is partly 

 hidden in one of the holes in the cartilaginous ring (Fig. 24. 5). 

 This is not the case with the small specimens at hand, in which
