(perhaps a permanent post-larval form of Metridium schiUerianum) and 

 Pelocoetes. Among the Gymnoblastea a new genus Dicydocoryne is 

 established in the family Corynidae. Four of the Coelentera of Chilka 

 Lake are casual visitors from the sea, three are periodic immigrants 

 from the Bay of Bengal, and nine are permanent inhabitants. Among 

 the last is a Virgularian not yet named. 



Australian Hydroids,*— W. M. Bale completes his report on the 

 Hydroids collected by the "Endeavour" from the Great Australian 

 Bight and other localities. Altogether sixty-four species or varieties 

 are represented in the collections, and of these twenty-two species and 

 four varieties have been ranked as new. This last part of the report 

 describes the following new forms : — Sertularel/a tasmaiiica, S. undulata, 

 S. pusilla, Nemertesia ciliata var. cruciata, Aglaophenia divaricata var. 

 cyst if era, and CladomrpeUa midUseptata. In two or three instances the 

 new material has enabled the author to describe the gonangia of species, 

 of which the gonosome was previously unknown. 



New Cornularid.t — S. F. Light describes Goruidaria minuta sp. n., 

 a minute Cornularid found at the Philippines growing on colonies of 

 Sijihonogoryia variabilis, to which it is attached by creeping, anasto- 

 mosing, threadlike stolons. The polyps are dirty white to light yellow, 

 with a maximum length of 2*5 mm., without spicules. Each stolon 

 has two or more endodermal canals in the homogeneous mesogloea. 

 The stolons are covered with a very thin, wrinkled, perisarc-like, horny 

 envelope, an extension of which forms a cup-like covering for the basal 

 portion of the polyps. Externally the species suggests Cornularia, but in 

 many respects it is also like Clavidaria. Perhaps it links the two. The 

 ectoderm of the tentacles contains in many places large numbers of oval 

 bodies, the nature of which, whether Zooxanthellge, or Protozoa, or 

 something else, remains obscure. 



New Species of Lithophytum.J — S. F. Light describes Lithophytuin 

 philippinensi^ sp. n. and L. riyidum sp. n., the first species of this genus 

 to be reported from the Philippines. The first species differs from all 

 others except L. ramosum and L. stuMmanni in the absence of spicules 

 from the polyps and from the cortex of the distal portion of the colony. 

 The second species is not far off, but is short, bushy, and stiff. 



Protozoa. 



Foraminifera of Kerimba Archipelago.§— E. Heron-Allen and 

 Arthur Earland continue their account |1 of the Foraminifera collected 

 by J. J. Simpson from this part of Portuguese East Africa, There is 

 a striking similarity between the general facies of the gatherings and
