A. Boulenger himself. Thus a reference to those Catalogues will tell the reader what animal is meant, if he is in doubt. In some cases, however, I have added, in brackets, commonly used synonyms. 2 I only give the Snakes which I have myself examined. Some of these have been previously examined for the lungs by Prof. Cope (these I have marked *) and a number of other species will be found in his paper (7). 3 In these elongated forms, with rare exceptions, such as Pygopus, the other dimensions of the lungs vary roughly in proportion to the length. In these lists " rud." signifies that the smaller lung is so small, not more than ,V the length of the larger, and usually much less, that it can be of no appreciable use. Sm. rud. (small rudiment) signifies that extra care will be needed to find the arsu dAti om fleiinnet d,t ihatusss biynt ceurtnstaiilgn nogir fiiofeipsce ent.h atth eI thrma®ch emaof ca sh \a dv$i sed by Copre , ("7') fD . 224' so |
