ECHINODERMATA. 
the sounds and fiords; (c) 12 spp. occur both in the Kattegat and in the 
Oeresund, but, except perhaps JEchinocardium cordatum, are not found in the 
other sounds and fiords ; {d) 7 spp. extend rather further, but are all want- 
ing in Svendborg Sound and Kiel Bay ; (e) 4 spp. occur in Svendborg Sound, 
of which Echinocyamus pusillus only is found in Kiel Bay. 
LtjTKEN, 1. (?. pp. 305-308, enumerates 23 Echinodermata as obtained in 
Spitsbergen by Heuglin’s expedition. The brief notice in Z. ges. Naturw. 
(n. s.) iv. p. 283, does not mention if any are new, 
Verrill gives a list of 60 species of Ophmroideay Astei'oidea, and Echi- 
noidea occurring in the Gulf of California and off Cape St. Lucas, and re- 
marks on their geographical distribution. The Holothurioidea are as yet un- 
known. Tr. Conn. Ac. i. pp. 693-596. 
Verrile, Am. J. Sc. (3) ii. pp. 357-362, notices many Echinoderms, 
Zoophytes, Annelida, &c. observed during the dredging operations connected 
with a fishing commission. 
On the Echinodermata dredged off Cuba and Florida by the U. S. Gulf- 
Stream Expedition, cf. Pourtales, Bull. Soc. Neuch. viii. pp. 386-389. A 
list of species is appended [^cf. Zool. Bee. vi. p. 639, and Arch. Sci. Nat, xli. 
pp. 83-90]. 
On a few Echinodermata &c. obtained near Port Macon, N. C., cf, E. 
Coues, P. Ac. Phil. 1871, p. 148. 
CRTNOIDEA. 
Beyrich, ^^Ueber die Basis der Crinoidea hrachiata^^ (MB. Ak. Berl. 
1871, pp. 33-66), chiefly treats of fossil species. 
Antedon and Pentacrinus. Structure described and compared with that of 
the PaliBozoic Crinoids. Wyville Thomson, P. R. Soc. Edinb. vii. pp. 415- 
418. 
Comatida mediterranea. On its minute anatomy, cf. 0, Grimm, Bull. 
P^tersb. xvii. pp. 3-9, plate. The interior of the fibrous layer of the nucleus 
contains a remarkable system of canals, which the author supposes to be 
connected with respiration. On the great similarity between its larval de- 
velopment and structure and that of the Bryozoa, cf E. Metschnikoft) Bull.

was republished in QCfv. Vet. Ak. 1869, pp. 729-731.

OPHIUROIDEA. 
T. Lyman (Illustrated Catalogue of the Museum of Comparative Zoology 
at Harvard College, No. 6. Supplement to Ophiuridee and A&trophytidce. 
Cambridge, U. S. A. : 1871. pp. 17, pis. 2) describes and figures several new 
species, with details of others. A list of the principal writings on the sub- 
ject is prefixed, supplementary to one published in 1865. 
The author maintains that all binomial names, whether pre-Linmean or 
not, should be retained, and that any author who transfers a species from 
one genus to another, ought to attach his own name to the alteration instead 
of that of the original describer[!].
