1932 112 p., several text figs, 17 plates, disbound (no covers).The paper consists of three parts, being an itinerary of the expedition, descriptions of (many) new genera, species and subspecies, and (by Lowe alone) additional records of other species collected. The plates, depicting many type specimens, are excellent, certainly better than in Keen's Seashells of tropical west America. Uncut, unopened. The plate and text blocks are separated from each other. Both, however are clean. Rather scarce.
