1. Five Japanese teieosts, Antennarius tridens, Pterophryne hystrio ranina, Hippocampus coronatus, H. mohnikei, and Microphis brachyurus were revealed to have no glomeruius in the kidney. 2. In these fishes, the nephron is only composed of the collecting duct and the second part of the proximal convoluted segment, whose first part is lacking completely, while these two parts of the proximal convoluted segment are always present in glomerular fishes. The epithelia of the proximal convoluted segment and the collecting duct bear a resembrance well morphologically to those of other teleosts. 3. It is notworthy that is Microphis brachyurus, the kidney envelopes the cardinal vein and the nephron exists only around it. This kidney is different from that of other teleosts in these points. In Hippocampus coronatus and H. mohnikei, the second part of the proximal convoluted segment richly branches out, this structure being considered as the most developed type in the aglomerular nephron. 4. In Antennarius tridens and Pterophryne hystrio ranina, the chromaffin cells are found on the wall of the cardinal veins in the kidney while they exist on the wall of the cardinal veins in the head kidney. Therefore the chromaffin cells are considered to be more related to the cardinal vein rather than to the head kidney.
