Gray, J. E. Synopsis of the species of Starfish in the British 
Museum (with figures of some of the new species) . Lon- 
don, J. Van Voorst, 1866 (published in 1867), 4to, pp. iv 
and 1-18, tabb. 1-16. 
In the ^Annals & Magazine of Natural History ^ for November 
and December 1840, Dr. Gray published a Synopsis of the 
Genera and Species of the Class Hypostoma (Asterias, Linn.),^^ 
and in the ^ Proceedings of the Zoological Society ^ for May 1847 
he described some new genera and species of Asteriadoi. The 
former paper was intended as a prodromus to a work giving- 
figures of all the genera and most of the species of the class ; but 
many things prevented the work from being proceeded with j 
and as several of the plates represent species figures of which 
have not liitherto been published. Dr. Gray now publishes them, 
accompanied by a synopsis, which is nearly the same as that 
published in 1840, but with synonyms added to the list of species. 
He mentions in the Introduction that many of Mr. Cuming^s 
specimens, on which some of the species were founded in his 
paper of 1847, were lost on the distribution of the Zoological 
Society's museum. The plates are perhaps the most beautiful 
that have been as yet published of Starfishes.

During a seven years^ sojourn amongst the Phillipine group of 
islands. Dr. Semper made large collections of natural-history 
objects, also obtaining, partly by his own labour, partly by the 
assistance of Mrs. Semper, many hundred coloured drawings of 
invertebrate animals. This volume on the Holothuroids is but 
the first of a scries which the author intends publishing on the 
Natural History of the Philippines, and it contains, in addition 
to a description of all the species met Avith by Dr. Semper, an
