With respect to the Cyprinodonts, several of the species inhabit 

 salt and fresh waters indifferently, the C. Hammonis being one of the 

 number. It was origiually discovered by Ehrenberg m the springs 

 of the Oasis of Jupiter Ammon, and subsequently in great plenty in 

 other districts of Egypt and Syria. M. Eloy found it in the waters 

 of Damascus, and Riippell statės that it is an inhabitant of all 

 parts of the Red Sea, and also of the fresh-water springs at Tor, 

 which have a temperature of 26į° of Reaumur or 91°'6 of Fahr. 

 This is also the temperature of one of the hot springs of Cannea in 

 Ceylon, inhabited by the Amhassis thermalis. M. Renaud, on seud- 

 ing examples of this Ambassis to Cuvier, stated that the heat of the 

 spring was 115° Fahr. ; but there is reason to infer, either that his 

 thermometer was incorrect, or that he took the temperature of the 

 feeding spring only. 



When Dr. Davy visited the springs in October 1817, the hottest 

 well raised the thermometer to 107°, but he was told that the heat 

 fluctuated, and had been observed as high as 110° F. There are in 

 all seven węlls, their temperatures being various, and that of one of 

 them as low as 86°. In one only, in which the thermometer stood 

 at 91°, did he observe fish. He thought it probable that all the 

 wells were supplied with water from the šame source (Davy's 

 Trayels in Ceylon, p. 44). 



In an exeursion from the south side of the Sea of Marmora to the 

 Asiatic Olympus, Mr. Poole obtained several Cyprinoids and soma 

 Gobies chiefly from Lake Apollonia or Apollonitis near Broussa, and 

 from the River Gemlek that falls into the Sinus Cianus. He also 

 caught some Trout on the summit of Olympus itself. The specimens 

 are unfortunately so much decayed that their original forms cannot be 

 ascertaiued with sufficient precision, but they have much resemblance 

 to the common Sahno fario of Linnseus, and likę it have two longi- 

 tudinal rows of teeth on the vomer, without a cluster on the front 

 of that bone. The Cyprinoids and Gobies are in good condition. 



Cyprinus Bithynicus, Ričhardson. 



The Cyprini resemble one another so closely, that it is matter of 

 extreme difficulty to determine the species when unaided by correetly 

 labelled specimens. One of Mr. Poole' s fish, caught in Lake Apol- 

 lonitis, has the four minute barbels of Cyprinus carpis, but differs 

 from that typical form in the great compression of its body, while 

 it does not agree so perfectly with C. elahis, hmtgaricus, Nord- 

 manni, and other species with deep bodies, described and figured 

 in the ' Histoire des Poissons,' as to be referable with confidence to 

 any of them. In general form, the origin of the barbels, position of 

 the fins, and numbers of their rays, as well as in the outline of the 

 preorbitar and ręst of the suborbitar scale bones, it corresponds more 

 closely vyith C.Jfavipinnis than with any other member of this group 

 noticed in that work ; but as Jlavipinnis belongs to the Indian Ar- 

 chipelago, a mimite comparison of specimens is necessary to esta- 

 blish their identity. Hence I have designated Mr. Poole's fish by a
