Holotype of Hydroides engi sp. nov., UWBM 118855, attached to the shell of a gastropod, Ranella washingtoniana, Cowlitz Formation, Big Bend locality, Washington State, USA. A. Overview and orientation of close-up views A 1, A 2. A 1. Close-up views of early stage of tube showing delicate flange-like peristomes almost coincident with whorl boundaries of the gastropod. A 2. Apertural view of tube showing slightly quadrate outline of outer surface contrasted with circular lumen of tube. A 3. Apical view of gastropod showing its protoconch and the early tube stage. A 4. View of tube showing basal flange and growth lines which are most distinct on the upper side bordered by low lateral crests.	Figure 2.

Paratype specimen of Hydroides engi sp. nov., UWBM 25241. A – A 2. Different views of tube coiled and wrapped upon itself. A. Showing poorly preserved bryozoan and eroded older portion of tube near bottom, with eroded remnants of another tube attached to its upper surface. Tube displays flattened upper surface in middle with slightly raised central thread, finally near top illustrates final transition from flat-topped tube to rugose rounded tube with vesicles / pustules; impression of the surface of a Murex sp. shell visible on right side of A 1, basal flange visible in lower part of A 2 along with flattened upper surface with median thread in center of A 2. B – B 2. Second paratype of H. engi, sp. nov., UWBM 118856. B. Lateral view; B 1. Upper view; B 2. Cross-section. C, C 1. Unidentified vermetid gastropod, UWBM 118853, attached to apical portion of Turritella sp. All from the Cowlitz Formation, Big Bend locality, Washington State, USA.	Figure 4.
