It would appear, from this singular arrangement of the end of the young stalk, that 

 L. annulatum is related to L. kefersteinii\ but the nuniber of its tentacles is considerably 

 smaller than in that species, and buds are developed less profusely. 



The following specimens probably belong to the present species ; but as neither of thcm 

 is associated with a Retepore I have thought it best to record them separately : 



416. J. On Schizoporella, 416. G. (slide). Stat. 321. 6° 5'. 5 S., 1 i3°3o' E., 82 Metres; fine grey mud. 

 130. P. With Valkeria tuberosa, 130. G. 2 , Stat. 164. t°42'.5. S., I30°47'.5 E., 32 Metres; sand, 

 small stones and shells. 



Each of the above specimens is represented by a single individual. 



416. J. is attached to the frontal wall of a zooecium of a species of Schizoporella. It is 

 seen sideways, in a position imfavourable for examination. lts general shape and size correspond 

 well with the specimens from Retepores. lts stalk shows distinct indications of annulation, and 

 has an expanded disc of attachment, without foot-gland. There is an advanced bud, on one 

 side, the tentacles of which appear to be 9, or about 9, in number. 



1 30. P. occurs on a Valkeria slide, but the Ctenostome had no doubt been growing 

 on some other object ; and its association with the Loxosoma on the same slide may have 

 been purely accidental. There is not sufficiënt reason to assume that it was really the "host" 

 of the Loxosoma. The specimen appears to agree closely with the preceding individual, and is 

 probably correctly referred to the present species. 



4. Loxosoma velatum n. sp. (PI. I, figs 8 — 10). 



24. D. On Retepora, 24. A. Stat. 53. Bay of Nangamessi, Sumba, o — 36 Metres; coral-sand ; 

 near the shore, mud. 



Calyx (without the expanded membranous margins) about 205 u. long, and (with the 

 marginsj about 198 u. broad; expanded laterally into a very broad, thin, velate margin, which 

 extends on to the distal part of the stalk. Length of calyx plus velum, 320;/. In young 

 individuals (fig. 9), in which the velum is not yet differentiated, the stalk appears to expand 

 widely as it joins the calyx. The calyx bears a varying number (less numerous in young 

 specimens) of cirriform organs, some of which may be branched. 4 or 5 of these organs are 

 generally present on each side ; the distal pair forming horn-like structures in the region of 

 the lophophore, and the others being borne by the edges of the velum. Buds not more than 

 three at a time, a nearly mature bud being accompanied by a small bud on its own side and 

 a bud of intermediate age on the opposite side. Tentacles apparently about 14 — 16, the 

 lophophore transversely elongated in the retracted condition. Stomach with the lateral lobes 

 barely indicated. Sexes separate ; a pair of testes or a pair of ovaries being present. Stalk, 

 without its velate portion, longer than the part of the calyx which contains the lophophore and 

 stomach; with small projecting papillae laterally; ending basally in a small disc of attachment: 

 with no foot-gland in the adult, but a well developed gland in the buds. 



Found attached to a species of Retepora.
