persistently in the burrows that I am forced to include them in 

 the fauna. They have not yet been studied by an arachnologist. 

 Another arachnid discovered in a gopher hole interests me greatly, 

 since it belongs to a group of small harvestmen {Phalangiidce) 

 which are characteristically cavernicole in this and other countries. 

 It is probably a new species, but congeneric with the cave har 

 vestmen {Phalangodes} found in Mammoth Cave, Ky., Wyan- 

 dotte Cave, Ind., and other great caverns in this country, although 

 some of the species are also found under deep stones, etc. I 

 have also found in a small cave near Istachatta, in eastern Florida, 

 a Phalangodes very closely allied to the gopher harvestman but 

 apparently distinct specifically. 



In my former paper Dr. Marx described a tick found on the 

 gopher under the name Amblyomma tuberculatum. The other 

 tick which is found constantly associated with the tortoise was 

 given a manuscript name, Ornithodorus americanus Marx. 

 This species has since been published in our Proceedings, with 

 out description, in the posthumous plate appended to the obituary 

 of our late lamented member. Dr.. Marx considered this tick 

 identical with a species found in the nostrils of mammals in Peru 

 and in Texas. At my request Dr. Marx made most careful 

 comparisons of my specimens with those from the horse and 

 the llama in his collection, but was unable to distinguish them 

 specifically. I regard this result as most surprising, since repeated 

 observation shows me that this tick does not attach itself to the 

 tortoise at any stage, but lives in the burrow like a bedbug, and 

 I find repeatedly the gravid females, plethoric with ova, burrow r ed 

 deep in the sand, beneath the floor of the burrows, as if incubating 

 their progeny. I have not yet, however, secured the larvae from 

 these females. I have in years past, on several occasions, taken 

 ticks from the bodies of the tortoise captu-red outside of their 

 burrows, and I supposed when my paper was written that some 

 of these would prove to be adults of Ornithodorus, but in hunt 

 ing up the material, some of it collected 15 years ago, I find an 

 abundance of specimens of the Amblyomma, but not one of the 

 Ornithodorus. I find it difficult to believe that any tick could 

 have a rostrum so constructed that it was capable of attaching 

 itself permanently to the nostrils of a mammal, while it could be 

 thrust into and withdrawn at will from the tough and leathery 

 hide of the Florida gopher. 



As a whole, the permanent connection of this insect fauna 

 with the economy of the tortoise, has been firmly established by 

 a more extended knowledge of the life histories of the several 

 species. Thus Philonthus gopheri has been found fairly 

 abundant in certain burrows, and a good series of its larva has 

 been secured. The larva of the Chelyoxenus has been found
