## TL;DR

This paper catalogs type specimens of recent mammals in the Naturalis Biodiversity Center, covering several mammal orders and designating lectotypes for two species.

## Contribution

The paper provides a detailed inventory of type specimens and formally designates lectotypes for two species.

## Key findings

- The study discusses 427 names, with 341 name-bearing types held by Naturalis.
- Lectotypes are formally designated for Sciurus erythrogenys and Macroxus schlegelii.
- The work continues the legacy of Chris Smeenk's research on the mammal collection.

## Abstract

This is the first part of a catalogue containing all known types in the mammal collection of Naturalis Biodiversity Center, Leiden, The Netherlands, covering the orders Monotremata to Rodentia in the sequence according to Wilson and Reeder (2005). The remaining orders will be treated in the second part later. The catalogue began in the early 1990s as a basic inventory using historic catalogues. Chris Smeenk, then curator of the mammal collection, researched the types until his death in 2017. The current authors continued his work, resulting in the present publication. We discuss in this first part 427 names. For 341 of these, Naturalis holds name-bearing types. For Sciuruserythrogenys Schlegel, 1863 and Macroxusschlegelii Gray, 1867 we formally designate the lectotypes.
