ment, where the rings which encircle them are not complete, a mem- 
brane taking their place in that portion of each tube which is con- 
tiguous to its opposite neighbour. Each bronchus, lower down, is 
composed of complete cartilaginous rings (vide fig. 2, p. 300). 
By many ornithologists Tantalus is arranged along with Platalea 
and Jéis, instead of with the Storks. Nitzsch, in his ‘ Pterylo- 
graphy,’ places it with Ciconia in his group PELARGI, separating off 
Platalea and Ibis to form the Hemietorripes. In the “ Revised 
List’ of the Animals in the Society’s Gardens, Mr. Sclater adopts 
the same arrangement. In my paper “On the Nasal Bones of 
Birds”’ *, it is mentioned that Platalea and Ibis are schizorhinal-— 
that is, have the external osseous nares split up in a manner there 
described, in which point they differ from the rest of Prof. Huxley’s 
Pelargomorphe, and therefore from Tantalus. 
There are many other structural peculiarities which make it per- 
fectly certain that 7’antalus is a member of the Ciconiidz, and not 
an aberrant one either.

Some of the most important it will not be 
They will be most easily appreciated 
in a tabular form, as thus represented :— 
In Ibis and Platalea. 
The skull is schizorhinal. 
The angle of the mandible is 
produced and recurved. 
The pectoralismajor muscle is 
simple, not being separable into 
distinct layers. 
The accessory femoro-caudal 
muscle is well developed. 
The semitendinosus muscle is 
muscular throughout. 
A small muscular belly is sent 
from the biceps cubiti to the 
tendon of the tensor patagii 
longus muscle. 
In Ciconia and Tantalus. 
The skull is holorhinal. 
The angle of the mandible is 
truncated. 
The pectoralis major muscle is 
in two layers, a superficial and a 
deep, easily separable one from 
the other. 
The accessory femorc-caudal 
muscle is absent. 
The semitendinosus muscle is 
tendinous for its distal half. 
No slip leaves the biceps cubiti 
muscle to join the tensor patagii 
longus. 
4. A Review of the British Marine Mites, with Descriptions 
of some new Species.

[Received March 16, 1875.] 
(Plates XLI. & XLII.) 
The marine Mites hitherto described either by British or foreign 
authors are very few in number ; and the descriptions seem for the 
most part to have been based on the observation of but few indivi- 
duals, often only one or two for each species. 
The animals have
