POPULAR SCIENCE REVIEW. 
may be cited Astronyx Loveni (?) while a single specimen of 
Ophiophyllum represents the great rarities. Of Astrocnida 
isidis , of which only three specimens were known, we have 
half a dozen. A large Pectinura recalls the shallow fauna of 
the East Indies; while a new Ophiernus brings to mind the 
Antarctic deep-sea forms. Finally, the supposed abundance of 
simple-armed Astrophytons is fully confirmed by the various 
species of Astrochema, and by a new species of Ophiocreas. 
The diligent search of Count Pourtales in the Straits of 
Florida, the Hassler expedition, the Challenger explorations, 
and the two expeditions of the Blake , have evidently brought 
up the majority of the species of Ophiurans ; for among the 
enormous mass of specimens this time obtained, the number of 
new species is not very great. 
The Hydroids and Bryozoa were mainly represented by the 
same forms as those collected last year, or in former coast survey 
expeditions in the Florida Straits. 
The corals, although abundant in specimens and species, 
probably contain but few un described ones. Very fine speci- 
mens of the larger, simple corals obtained by the Challenger 
expedition, which were never found in our earlier dredgings in 
the Grulf of Mexico, or the Straits of Florida, were dredged 
here, such as Flabellum, Trochocyathus, Ceratotrochus, etc. 
Several of the deep-sea Actinia?, described by Moseley, were 
obtained, generally attached to sponge spicules, Grorgoniae, or 
stems of Umbellarise. 
The Alcyonarians were also very abundant, and among them 
we expect to find many novelties. Little can be said of them 
at first view, as the deep-water forms have thus far received 
but little attention. One form, growing in a regular spiral, 
with equidistant branchlets on the outer side of the spire, 
seems, by this mode of growth, to differ from anything pre- 
viously known in that order. Several fine specimens of Umbel- 
laria were obtained. 
Among the Annelids, the tubicolous Annelids are by far the 
most striking, from the exquisite beauty of their tubes, composed 
of siliceous spicules, and dead Pteropod shells, and from their 
strange associations with Corals, Grorgoniae, sponges, and even 
molluscs. A species of Phorus was frequently accompanied by 
a large Annelid, comfortably established in the axis of the 
shell, with the head close to the aperture. 
Among the Crustacea we found again the Bathynomus 
giganteus , A. M. Edw., discovered last year. We also brought 
up from 734 fathoms a Pycnogonum, measuring not less than 
two feet al©ng the legs, when fully extended ; a fine Astacus 
zealacv.8\ and, from 416 fathoms, a magnificent species, allied 
to Nephrops, blind, but with rudimentary eye-stalks. An in-
