Hypsilophodon Foxii ; and in 1882 a still more iihportant memoir on 

 the same species was published in the ' Philosophical Transactions.' 



In 1874 and 1876 Mr. Halke showed that a certain bone of 

 Iguanodon, which had been regarded as a scapula, was really a part 

 of the pelvis ; and, indeed, it proved to be the remarkable pubis of 

 that reptile, which so nearly resembles that of a bird. 



In 1879 the two genera, " Poildlopleuron and Megalosaurus, were 

 shown by Mr. Hulke to be one and the same Dinosaurian genus. In 

 the same year he described the remains of a new Wealden Dinosaur 

 under the name of Vectisaurus Valdensis ; and in 1880 he made 

 known one of the most perfect Iguanodons discovered in this country 

 which had been found in the Kimmeridge clay of Cumnor ; this was 

 named Iguanodon Prestwichii. 



In the following year there appeared in the ' Philosophical Trans- 

 actions ' Mr. Hulke's memoir on Polacanthus Foxii. This remarkable 

 Dinosaur, the name for which had been suggested by Sir R. Owen, 

 has a large dermal shield spread out above the iliac bones in such a 

 way as to form a kind of carapace over the lumbar and sacral regions ; 

 besides this, large spines and scutes were attached to other parts of 

 the body. 



Mr. Hulke's presidential addresses to the Geological Society, 

 1883-4, formed an important contribution to our knowledge of 

 reptilian osteology, and especially threw light on the structure of the 

 shoulder girdle in Plesiosaurs and their allies. 



The Iguanodont remains found in England have been more or less 

 fragmentary, and discoveries made by other workers helping to 

 elucidate their structure were hailed by Mr. Hnlke with satisfaction ; 

 no one more heartily rejoiced than he did when the rich treasures of 

 the Belgian Wealden rocks were brought to light by the geologists of 

 that country, and they made known the discovery of the series of 

 magnificently perfect Iguanodon skeletons, several of which now 

 adorn the Museum of Natural History at Brussels. 



Mr. Hulke was for many years on the Council of the Geological 

 Society, and the high esteem in which he was held by the leading 

 geologists of tlie day, as well as their thorough appreciation of his 

 palaeontological work, found expression by their electing him, in 

 1882, to fill the Presidential chair of their Society, and, in 1887, by 

 their presenting him with the Wollaston Gold Medal, the greatest 

 honours it was in their power to bestow. In 1891 he was elected 

 Foreign Secretary of the Geological Society, which office he still held 

 at the time of his decease. 



Beloved and respected by all who knew him, Mr. Hulke will long 

 be lamented as a Christian gentleman.
