HOMALONOTUS, Koenig. 



On May 25th, 1836, Sir Roderick Murchison announced to the 

 Geological Society of London that Sir John Herschel had dis- 

 covered Trilobites in a rock which occurs to the north of the Cape 

 of Good Hope, tlie specimens having been collected, apparently, 

 by Dr. Smith, the naturalist and explorer of South Africa. Sir 

 Roderick Murchison descrilKd the Ti-ilobites later as belonging to 

 the species Galymoie hh( mciilxiclii and Homalonofns ho'schrli, 

 n. s.'; a further species, he states, approaches G. tristani. Salter^ 

 remarks that the Cape Hontahynotus is distinct from the European 

 species. H. Jcnigldi was recorded by Dr. Sandberger^ on the 

 authorit.y of de Verneuil from the Cape, but Salter lor. vit. states 

 that this is an ei-ror. Dr. Sandl:>ei'ger''s H. crassicaudcf* from the 

 Cederbergen is also an error of identification. Salter in 185G 

 refigured the H. Jwrscheli together with the head, which is want- 

 ing in Murchison's specimen, from material sent him by Mr. A. G. 

 Bain ; in the residue of the Bain collection and in other material 

 in the Albany Museum I find no less than four good species dis- 

 tinct from H. /i/'j'srJirl/. In 1897, Freeh figured a large tubercu- 

 late species under the name of H. peraniiatus^ , and in 1904 Lake 

 described three new species — H. 9t*^r/iw.s-, H. colossus and 5^. .<*/>." 

 There is still another variety in the typical H. hcrschrli which, if 

 the illustrations accompanying Saltei'^s paper are correct, and Lake
