with the open side against each other, and between the funnels there 

 is a granulated mass. 



For the description of the calcareous deposits, only two small 

 pieces of skin imbedded in balsam are present, as the deposits in 

 the specimens themselves have unfortunately been dissolved. There 

 are two different sizes of anchors and plates (Fig. 15. 1-2). The 

 larger anchors measure ca. 220 ^ in length and 140 jn in width, 

 and the smaller ones ca. 120 ^ x 65 /a. The stock is finely tooted 

 and on vertex there are minute knobs, 3 — 5 in the large anchors 

 and 1 — 3 in the small ones. The large anchor-plates measure ca. 

 170 /a in length and ca. 140 ^ in width. The shape of the plates 

 is varying. Most of the plates are narrow in the posterior end (Fig. 

 15. 3), but some few in each preparation are more wide (Fig. 15. 5). 

 The articular hole is smooth and the bridge has some few knobs. 

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

 small plates (Fig. 15. 4) measure ca. 110 /tv in length and 160 [i 

 in width, and their shape is quite as that of the large anchor-plates 

 with the wide posterior end. In the one preparation there are some 

 few anchors of a third size. These anchors (Fig. 15. 6) measure 

 ca. 270 f.i in length. The miliary granules (Fig. 15. 8) are rosettes, 

 which are spread all over the skin. 



This species is the only species of Synaptula which is known 

 with certainty to have 15 tentacles, but it agrees so well with the 

 other oriental species of the genus that there is no doubt that it 

 belongs to it. That it cannot be synonymous with Semper's 

 Synapta nigra, as assumed by Clark in "The Apod. Holoth." pag. 

 81, was pointed out by Th. Mortensen (Op. cit.). 



Synaptula rosea n. sp. 

 Off Jolo. 21. III. 1914. 15 fms. One specimen. 



The specimen at hand measures ca. 13 cm in length and 0,5 

 cm in diameter. The colour is a bright reddish. It has 14 ten- 

 tacles, but as there is but one specimen present, it is not possible 

 to say whether this number is the normal, or the species has 13 

 or 15. The tentacles are ca. 1,2 cm long, with ca. 20 pairs of digits 

 united by a web. On the oral disk there are distinct eye-spots. 

 The calcareous ring (Fig. 15. 14) is pure white, without any traces
