London, 1889, pp. 452-474, plates xlvi.-xlix. I quote this paper here because, as explained, the present one is really a continuation of it, and I shall have occasion to refer back to it. Some other references will be found in it. § III. List of Snakes examined 2. ouuuruei JL Fam. Fam. Suborder I Fam. Fam. Fam. Fam. Fam. Fam. CATODONTA. EPANODONTA. 1. COLUBRIFORMIA. UEOPELTID.E.

P. 473, 1. 14, for "mesentery and ligaments^ read mesentery and median ligaments. Fig. 7, erase v.om, v.om'. Fig. 33, for 4 read 3. Fig. 46, the space on the right side of the figure into which the spleen and oesophagus project should be marked 2' and similarly Fig. 47, for 2 and 3 read 2' and 3 (on the left side of the figure). With regard to figs. 42 and 43 see below, § VII. (iii.) note. Further, since the description of the Crocodile was written, I bave, thanks to the generosity of Mr. S. F. Clark, of Williams College, Mass., been able to cut sections of a considerably younger stage (viz. a 35-days Alligator). This, while confirming the other opinions expressed in the previous paper, makes it clear that there is originally a " Foramen of Winslow " in the normal position, so that from the 7th to the 18th lines inclusive on page 470 of (5) should be struck out. Lastly, since p. 465 of that paper was written, I have found that certain Scincoid Lizards are as to the relations of their right lungs and liver intermediate between the Teiidre and other Lizards; while Acontias meleagris agrees with most Lizards, Anguis fragilis, Chalcides mionecton, and apparently Acontias mono-dactyla have their " pulmohepatic recess " not extending into the region of the lungs. So that a section through the lungs resembles fig. B on that page, and one behind the lungs shows the right lobe of the liver attached as in fig. A. 2 For explanation see § V. |
