group,” but is distinguished from any known member by what appear 
to be definite characters. He points out, however, that we are at pre- 
sent, owing to the want of series of specimens, in the stage of making 
species. When larger series are before us, “ another part of our work 
will begin.” 
Deep-Sea Holothurians from the Indian Ocean.* — Dr. J. H. Tall 
Walsh has a report on the eighteen species dredged in deep water by 
the Survey Steamer ‘ Investigator.’ Amphigymnas (A. multipes) is a new 
genus of the Deimatidae, with an ovoid body and narrow tail-liko 
extremities ; Apodogaster ( A alcocJci) is a new genus of Psychropotidae, 
with a long, flat and worm-like body ; Pannychia wood-masoni, Bentho- 
dytes ovalis, B. gelatinosa , and Trochostoma andamense are new species. 
Ccelenterata. 
Stephanophyes. f — Prof. C. Chun begins a monograph on the Sipho- 
nophora of the Canary Islands with an account of Stephanophyes superba 
and the family Stephanophyidae. He apologizes for trenching on a 
province which Haeckel has recently surveyed in his * Challenger ’ 
Report, but believes that he has something new to say about Stephano- 
phyes , and differs moreover from Haeckel in regard to the phylogeny of 
Siphonophora. 
Stephanophyes superba , allied in habit to Pray a (or Lilyopsis ), is the 
most complicated of Calycophoridae. It has two kinds of “ Fangfaden ” ; 
one set inserted in the usual fashion at the base of the stomach-sacs, and 
bearing the reniform batteries characteristic of Calycophoridae, the other 
set attached to mouthless polypoid appendages with aberrant acorn-like 
stinging-knobs. 
The stem bears anteriorly the chief swimming-bells, then groups 
consisting of gastral-polyp, covering protective flap, several male or 
female gonophores, and a special swimming-bell, while between each 
group there are palp-like polyps with heteromorphous stinging-knobs. 
As to the position of Stephanophyes among other Siphonophora, the 
following classification may be noted.

III. Fam. Stephanophyidae Chun. 
IV. Fam. Desmophyidae Haeck. 
Y. Fam. Polyphyidae Chun. 
The family Stephanophyidae, which includes the single genus 
Stephanophyes Chun, is characterized as follows. The swimming-bells 
are rounded, not angled, with dichotomous oil-reservoirs, disposed with
