P alee ontology. — Mr. S. H. Scudder has recently described a new fossil but- 

 terfly (Satyrites Reynessii), from a tertiary deposit at Aix, in Provence. The 

 fossil is a natural imprint, and its state of preservation shows that it had 

 undergone great maceration in quiet water before being covered up by the 

 deposits which have preseived its most essential features. The insect is 

 placed on its side, with the wings elevated one against the other, the legs 

 spread out as if it were suspended, the spiral proboscis unrolled, and the 

 antennae lowered in the same direction as the legs. The nearest living repre- 

 sentative of this fossil butterfly are natives of India. 



Mr. A. G. Butler has described, in the " Geological Magazine " for January, 

 a new fossil butterfly (Palceontina Oolitica) belonging to the family N ymphalid 'ce , 

 This insect belongs to a group completely tropical, its nearest allies being 

 tropical American genera. It is interesting as belonging to the highest family 

 of butterflies, and to a sub-family intermediate in character between two 

 others — namely, the Satyrince and Nymphalince, but it is especially interesting 

 as being the oldest fossil butterfly yet discovered. 



Prof. O. C. Marsh, who has added largely to our knowledge of the fossil 

 vertebrata of North America, announces the discovery of fossil quadrumana 

 in the Eocene strata of Wyoming. These remains closely resemble, especially 

 in many of the larger bones, some of the Lemurs, while the anterior part of 

 the lower jaws is similar to that of the marmozets. The teeth are more 

 numerous than in any known quadrumana. 



Prof. Marsh also describes a new carnivore from the tertiary strata of 

 Wyoming, named Oreocyon latidens. The remains indicate an animal about 

 as large as a lion : the canine and premolar teeth of the lower jaw somewhat 

 resemble those in the hyaena, but there were only two incisors in each ramus. 



One of the most interesting discoveries of recent years has also just been made 

 known by Prof. Marsh. It belongs to a new sub-class of fossil birds (Odon- 

 tornithes). The remains were discovered in the Upper Cretaceous Shale of 

 Kansas. The type species of this group is called Ichthyosis dispar: it has 

 well-developed teeth in both jaws, very numerous, too, and implanted in distinct 

 sockets. The possession of teeth, and also of bi-concave vertebrae, imply that 

 these remains cannot be placed in the present group of birds, and hence a new 

 sub-class has been formed. The bird was no larger than a pigeon ; it was 

 carnivorous, and probably aquatic. The fortunate discovery of these interest- 

 ing remains is an important gain to palaeontology, and does much to break 

 down the old distinctions between birds and reptiles, which the Archceopteryx 

 has so materially diminished. 



Prof. H. A. Nicholson has described a new genus of Tubicolar Annelides, 

 {Conchicolites) for some forms found growing upon the shells of Orthocerata 

 in the Lower Silurian rocks of the north of England. The tubes in this genus 

 agree with those of the modern Serpulce in being calcareous, and they differ 

 altogether from those of the extinct genus Cornulites in being altogether 

 destitute of any cellular structure. 



The affinities of Calceola sandalina, one of the most problematic of fossils, 

 have been lately discussed by the Rev. T. R. R. Stebbing. It has been referred 

 to the Conchifera, Rudistes, and Brachiopoda, but Mr. Stebbing agrees with 

 Suess and Lindstrom in placing the genus among the Zoantharia rugosa. He 

 refrains from giving the convenient name of coral to the Calceola, because 

 Lindstrom, following Agassiz, gives reasons of some weight for separating the 

 Rugosa from the true polypes, and conjectures them to be allied rather to the 

 Hydrozoa than to the Anthozoa. 



Dr. Anton Fric has described a new crustacean from the Polirschiefer, near 

 Bilin, in Bohemia, which he names Palamon exul. The discover}' is remark- 

 able, on account of its being a marine crustacean in a fresh-water deposit. 



Mr. H. Hicks has described a number of new species of fossils from the 

 Tremadoc rocks of St. David's, South Wales, which prove that these rocks are 

 nearly allied to the lower part of the Tremadoc rocks of North Wales. The
