Aphelocoma coerulescens
15 Apr. 1957
of right lobe liver. Turns a little left and descends in about mid-dorsal line to end of coelon, then turns ventral, a little right, to bottom of right liver lobe. Next dorsal + posterior, and again ventral, making a coil of 2 1/2 loops. Included is another dorsal descending part, to a ventral anterior ward part. The latter goes anterior but the loops, to about liver, turns to left & loops between abdomen + gizzard, then goes toward right. A little right of mid-dorsal line, it goes to dorsal body wall and turns straight posterior. At this turn is a fold of intestinal lining which maybe a valve. Extends into large intestine or colon from here.
Large intestine: from clove-rationed turn, which is a sharp right angle, the gut goes directly to cloaca. The intervening section is 30 mm. long.
Midway, & 15 mm. below turn, paired caeca come off. (Tried a thread at fold) There is no valve structure evident at level of caeca. Intestinal wall definitely becomes thicker here, tho, and is thick for rest of its length.
Caeca: Paired, on ventro-lateral side walls of gut. Openings are very small, almost obscured. 6 mm. long. Extend anteriorly along intestine, bound to it by connective tissue
Misc: There is a cord from right lobe
